Meso-scale modelling of 3D woven composite T-joints with weave variations [PDF]
A meso-scale modelling framework is proposed to simulate the 3D woven fibre architectures and the mechanical performance of the composite T-joints, subjected to quasi-static tensile pull-off loading. The proposed method starts with building the realistic

Finite element based surface roughness study for ohmic contact of microswitches [PDF]
Finite element method (FEM) is used to model ohmic contact in microswitches. A determinist approach is adopted, including atomic force microscope (AFM) scanning real contact surfaces and generating rough surfaces with three-dimensional mesh.

Study on the Spalling Fault Degradation Mechanism and Dynamic Model of Gear Tooth Surfaces
Under the action of alternating load, the initial crack on the gear tooth surface would inevitably initiate and gradually evolve into spalling and other faults. It has a serious impact on the transmission system.
