Available in PDF, EPUB and Kindle. Book excerpt: This study is on the fracture behaviour of short fibre polymers on which fracture toughness (K) is calculated through some testings with the help of LEFM (Linear Elastic Fracture Mechanics) theory. The materials used were Fortron R PPS, Ryton R PPS and PBT. The variables controlled were: notching technique (broaching, femtolaser, pressing and tapping), thickness of the sample (6mm and 9mm) and testing speed (low-speed and high-speed). After the samples were broken, they were analysed using an optical microscope and SEM microscopy. The results found that Fortron and Ryton behaved elastically but PBT was on the verge of being discarded as it might be unsuitable for LEFM analysis. The analysed pre-notches were all equivalent in their radius, but notching depth was higher when using the femtolaser. Notching radius in broaching was bad in comparison to the other techniques. There were no significant differences between the values for fracture toughness between the different notching techniques, making this tapping and pressing very cost-efficient. When analysing the differences on sample thickness effects it was clearly shown that the 6mm samples had much higher fracture toughness, with the main hypothesis being that fibres were more oriented. Finally, no significant differences were shown on testing speed influence, despite being all main values lower on low-speed tests.

The rise in materials failure by fracture has forced scientists and researchers to develop new higher strength materials for obtaining higher fracture toughness. Therefore, further knowledge and insight into the different modes of fracture behavior of FRP composites are critical to expanding the range of their application.

Download or read book The Theory of Critical Distances written by David Taylor and published by Elsevier. This book was released on 2010-07-07 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Critical distance methods are extremely useful for predicting fracture and fatigue in engineering components. They also represent an important development in the theory of fracture mechanics. Despite being in use for over fifty years in some fields, there has never been a book about these methods – until now. So why now? Because the increasing use of computer-aided stress analysis (by FEA and other techniques) has made these methods extremely easy to use in practical situations. This is turn has prompted researchers to re-examine the underlying theory with renewed interest. The Theory of Critical Distances begins with a general introduction to the phenomena of mechanical failure in materials: a basic understanding of solid mechanics and materials engineering is assumed, though appropriate introductory references are provided where necessary. After a simple explanation of how to use critical distance methods, and a more detailed exposition of the methods including their history and classification, the book continues by showing examples of how critical distance approaches can be applied to predict fracture and fatigue in different classes of materials. Subsequent chapters include some more complex theoretical areas, such as multiaxial loading and contact problems, and a range of practical examples using case studies of real engineering components taken from the author’s own consultancy work. The Theory of Critical Distances will be of interest to a range of readers, from academic researchers concerned with the theoretical basis of the subject, to industrial engineers who wish to incorporate the method into modern computer-aided design and analysis. Comprehensive collection of published data, plus new data from the author's own laboratories A simple 'how-to-do-it' exposition of the method, plus examples and case studies Detailed theoretical treatment Covers all classes of materials: metals, polymers, ceramics and composites Includes fracture, fatigue, fretting, size effects and multiaxial loading

Available in PDF, EPUB and Kindle. Book excerpt: Over recent years there has been a tremendous upsurge in interest in the fracture behaviour of polymers. One reason for this is the increas ing use of polymers in structural engineering applications, since in such circumstances it is essential to have as complete an understanding as possible of the polymer's fracture behaviour. This book is designed to meet the requirements of those who need to be informed of the latest developments in the field of polymer fracture. It is written particularly for research workers but it should also prove invaluable for advanced students taking final-year undergraduate or postgraduate courses. The main emphasis is upon the use of fracture mechanics in the study of polymer fracture but this approach is then developed to cover the micromechanisms of the fracture process. Particular prominence is given to the relationship between structure, mechanical properties and the mechanics and mechanisms of fracture. The first chapter is a brief introduction which has several aims. One is to introduce polymers to the reader who does not have a strong background in the subject and another is to provide background material that will be used at later stages. The book is then split into two main parts: the first deals with the mechanics and mechanisms whilst the second is concerned with materials. In Part I phenomena such as molecular fracture, fracture mechanics, shear yielding and crazing are covered from a general viewpoint.

Download or read book On the anisotropic plastic behaviour of short fibre reinforced thermoplastics and its description by phenomenological material modelling written by Felix Dillenberger and published by Springer Nature. This book was released on 2019-10-21 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: A requirement for the safe design of thermoplastic parts is the ability to precisely predict mechanical behaviour by finite element simulations. Typical examples include the engineering of relevant components in automotive applications. For this purpose adequate material models are essential. In this context, the present work introduces a material modelling approach for short fibre reinforced thermoplastics (SFRTPs). SFRTP parts are processed cost-effectively by injection moulding and show a varying degree of anisotropy due to the locally inhomogeneous fibre distributions that arise during the moulding process. The presented material model considers linear-elastic behaviour and non-linear orthotropic stress-state dependent viscoplastic deformation for arbitrary fibre distributions. The constitutive equations are verified with the experiments of a PPGF30 material regarding different stress-states and orientations.

Book excerpt: The book aims at giving an overview of current methods in engineering mechanics of FRP components and structures as well as hybrid components and structures. Main emphasis is on basic micro and macro mechanics of laminates. Long as well as short fibre composites are studied, and criteria for different kinds of rupture are treated. Micromechanical considerations for material characterization and mechanisms of static ductile and brittle rupture are studied, as well as FRP structures under thermal and dynamic loading programs. Optimum design and manufacture situations are described as well. The book makes designers familiar with the opportunities and limitations of modern high quality fibre composites. Practical engineering applications of the described analytical and numerical methods are also presented.
