This book was released on 1988 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biaxial strain-hardening behaviors of aluminum, ?-brass, and austenitic stainless steel are characterized in plane and equibiaxial deformation paths using a novel low-cost biaxial device. These tests are complemented by conventional uniaxial tensile tests and by complex strain path studies consisting of uniaxial tension after biaxial pre-strain. The experimental results are analyzed and compared using two criteria of plasticity: von Mises and Hill. It is shown that different stress-strain curves obtained under different strain paths could not be correlated with the phenomenological yield criteria.

Download or read book Strain Hardening Effects on Fracture Toughness and Ductile Crack Growth in Austenitic Stainless Steels written by P. Balladon and published by . This book was released on 1985 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of cyclic and monotonic strain hardening on fracture toughness and ductile crack growth properties of 316 L stainless steel is determined using JIc and J-R curves. Cyclic strain hardening is performed by cyclic loading at different levels during precracking of specimens used for J-R tests. Monotonic strain hardening is done by controlled hot rolling of plate steel. The results obtained show that the fracture toughness is decreased by both cyclic and monotonic strain hardening. This decrease mainly affects crack initiation resistance (JIc) in the case of cyclic loading and only slightly influences crack growth resistance (dJ/da). For monotonic strain hardening, both JIc and dJ/da are strongly reduced at room and elevated temperatures. An attempt is made to determine the main factors responsible for these effects.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sheet metal forming processes are widely adopted to produce panels, tubes, profiled parts in manufacturing industry. The numerical simulation of the forming processes requires accurate constitutive models of material. In many sheet metal working operations such as stamping, hydroforming, ..., large strains and intermediate strain rates can be reached under biaxial strain or stress states. The objective of this work is to show the potential of the biaxial in-plane tensile test to characterize the hardening behaviour of metal sheets up to large strain levels. By numerical investigation, an optimal cruciform shape is designed to obtain large equivalent plastic strain, up to 30%, at the central zone under equi-biaxial strain path. As expected, the initial cracks of tested specimens are always observed at the central zone. Then, quasi-static and dynamic biaxial tensile tests on in-plane cross specimens have been performed on a dedicated servo-hydraulic machine. These biaxial tensile tests have been carried out on aluminium alloy AA5086 to validate the identification methodology of hardening behaviour under biaxial loading. This alloy has been chosen since its hardening behaviour is not dependent on the strain rate. Digital Image Correlation (DIC) technique is used for strain measurement. The parameters of isotropic hardening models are identified by inverse analysis based on the finite element model of the biaxial tensile test. Three yield criteria of Mises, Hill48 and Bron and Besson are compared for the parameter identification of different hardening laws. It is shown that the hardening law identified by biaxial test is precise only if an appropriate yield function is preliminarily determined. The biaxial flow stress curve identified with Bron and Besson yield function have been found in good agreement with the experimental flow stress curve obtained from uniaxial tensile tests. For biaxial tests at intermediate strain rates, damping layers are adopted to reduce oscillations on force versus time curves. The comparison of flow stress curves, identified from quasi-static and dynamic biaxial in-plane tensile tests on the non strain rate-dependent material AA5086, validates the identification methodology of strain-rate dependent hardening models. Finally, the proposed methodology is applied to the hardening characterization of a strain-rate dependent Dual Phase steel DP600 at room temperature. Identified biaxial flow stress curves have been compared with uniaxial ones for different strain rates ( . = 10-3s-1, 10-1s-1 and 101s-1). DP600 steel exhibits the same positive strain rate sensitivity for uniaxial and biaxial strain states. The biaxial flow stress curves identified on the basis of Ludwick and Voce hardening models are close, up to equivalent plastic strains of 30%. The benefits of the proposed methodology, based on a biaxial in-plane tensile test carried out on cross specimen, are clearly shown since the hardening behaviour identified in this case for large strains (up to 30%) is very different from the one identified from uniaxial tensile test on a smaller strain range.

Available in PDF, EPUB and Kindle. Book excerpt: A microstructural approach has been used to explain the deformation characteristics which influence the formability of aluminum alloy sheet materials. Optical metallography and transmission electron microscopy were used to study the response of various aluminum alloys to uniaxial and biaxial deformation. The predominant strengthening mechanisms for a given alloy had the strongest effect on strain localization and biaxial strain hardening behavior. Dispersion-strengthened alloys displayed a wavy slip mode, and high levels of strain hardening and resistance to strain localization. Precipitation or solid-solution-strengthened alloys exhibited more localized deformation and lower capacities for biaxial strain hardening.

This book was released on 1965 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanical properties of austenitic and martensitic stainless steels have been the subject of numerous research papers. The most complex types of materials, however, are the semiaustenitic steels which transform from austenite to martensite during plastic deformation. The most common commercial material which makes use of this characteristic is AISI Type 301. The research reported here had as its goal the determination of the mechanisms which control strain hardening and plastic deformation in commercially produced Type 301. The primary research tools used to reveal the mechanisms of deformation were the measurement of martensite forming during plastic deformation and the examination, by electron transmission and electron diffraction, of tension specimens deformed to various increments of plastic strain.

Available in PDF, EPUB and Kindle. Book excerpt: Duplex Stainless Steels (DSSs) are chromium-nickel-molybdenum-iron alloys that are usually in proportions optimized for equalizing the volume fractions of austenite and ferrite. Due to their ferritic-austenitic microstructure, they possess a higher mechanical strength and a better corrosion resistance than standard austenitic steels. This type of steel is now increasing its application and market field due to its very good properties and relatively low cost. This book is a review of the most recent progress achieved in the last 10 years on microstructure, corrosion resistance and mechanical strength properties, as well as applications, due to the development of new grades. Special attention will be given to fatigue and fracture behavior and to proposed models to account for mechanical behavior. Each subject will be developed in chapters written by experts recognized around the international industrial and scientific communities. The use of duplex stainless steels has grown rapidly in the last 10 years, particularly in the oil and gas industry, chemical tankers, pulp and paper as well as the chemical industry. In all these examples, topics like welding, corrosion resistance and mechanical strength properties (mainly in the fatigue domain) are crucial. Therefore, the update of welding and corrosion properties and the introduction of topics like texture effects, fatigue and fracture strength properties, and mechanical behavior modeling give this book specific focus and character.
