Abstract: Based on Mindlin displacement solution and Winkler’s assumption, the stress distribution formula of the internal anchorage section of full-length Injected bolt are deduced. The transmission law, attenuating characteristic of the shear stress are studied and then compared with the results from the test. It indicates that these two analytic solutions are agreed with the results from the test in the main. A reference principle for the analysis of the shear stress on the first and second interfaces of the anchorage section through model tests is provided.

Abstract: The site predominant period should be changed because of soil softening, which is an important parameter to reflect the dynamic characteristics of the site. In this paper, in order to acquire the theoretical solution to the site predominant period, the actual horizontal site has been simplified into two-particle system. And the influence that caused by the thickness and location of the weak layer on the site predominant period, has been analyzed.

Abstract: Analytical modelling of deep drawing process is of value in preliminary process design to illustrate the influence of major variables including friction and strain hardening on punch loads, cup dimensions and process limits. In this study, analytical models including theoretical solution and a series of finite element models are developed to account for the influences of process parameters including friction coefficient, tooling geometry and material properties on deep drawing of metal cups. The accuracy of both the theoretical and finite element solutions is satisfactory compared with those from experimental work.
