Book Modeling of Strain Rate Effects on Clay in Simple Shear

Download or read book Modeling of Strain Rate Effects on Clay in Simple Shear written by Byoung Chan Jung and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is the development of a new constitutive model to describe the behavior of cohesive soils under time dependent loading. In the work presented here, the modified SIMPLE DSS model is expanded to account for the effects of strain rate on clays in simple shear conditions. The response of clay soils is highly dependent on the rate of strain for both effective stress path and stress-strain behavior. The undrained shear strength is strongly influenced by strain rate both in monotonic and cyclic simple shear tests. Nevertheless, the few available experimental results cover a very limited range of loading conditions and rates. The existing literature established that the soil response display a unique relationship between shear strength and log scale of strain rate. To include the effects of strain rate, the modified simple effective stress model starts with two assumptions: (1) a specific shear strength corresponds to a specific strain rate in a unique relation; and (2) the effect of strain rate does not change the failure envelope. The proposed model is developed from the original SIMPLE DSS model, based on an effective stress formulation in a reduced stress space, and utilizing concepts related to the framework of bounding surface plasticity. The proposed model evaluation was carried out comparing model simulations with results of simple shear tests on Boston Blue Clay and San Francisco Young Bay Mud. The model capability is useful especially in strain rate dependent responses for both monotonic and cyclic behavior, including irregular loading and step-changed condition. It was found that undrained shear strength in simple shear is directly related to strain rate effects and the responses in cyclic test show the more rate dependent behavior than those in monotonic test. The proposed model is able to predict the increase in undrained shear strength for higher strain rate.

Book Factors Affecting the Long Term Strength of Compacted Beaumont Clay

Download or read book Factors Affecting the Long Term Strength of Compacted Beaumont Clay written by Roger Green and published by . This book was released on 1986 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes results of an ongoing study of the stability of embankments constructed of highly plastic clays in Texas. Previous studies showed that such embankments failed by sliding many (10-30) years after construction and that the apparent shear strengths were substantially lower that the long-term shear strengths determined on the basis of laboratory tests on compacted specimens. This report presents the finding of several series of tests performed to understand better the reasons for the discrepancies between field and laboratory shear strengths. Triaxial shear tests were performed to measure the effective stress shear strength parameters on (a) undisturbed specimens taken from actual slopes which had failed, (b) specimens prepared by consolidating soil from a slurry in the laboratory, and (c) specimens prepared by packing (remolding) soil into a special mold in the laboratory. In addition, residual shear strengths were determined on conventional compacted specimens.
