Adopting cement with sand to make intermittent cracked Rock-like samples, this article, through cracked samples with different cracked obliquity is tested with WDT-1500 multifunctional material test apparatus, study the mechanics characteristic and the destruction properties of rock mass, which under the combined action of cyclic load and the static load. Using computer processed the experimental...
This paper mainly investigates the carbon material femoral head which is used in the semi-hip replacement. Firstly the 3-D finite element model of the acetabula contacted with the prosthesis of different materials were established and calculate the acetabula's cotacted stress. Thought comparing the contacting stress of the acetabular, the effect of different material with quite different property...
In this study, shear horizontal gap waves propagating in layered piezoelectric structures with initial stress is investigated analytically. The boundary conditions imply that the displacement, shear stress, electric potential, and electric displacement are continuous across the interface between the layer and the substrate. The electrically open conditions at the interface between the air and the...
