Numerical simulation of surface crack propagation considering the crack closure effects and the three-dimensional stress constraints;

The plastic zone size of the crack tip is relative to three dimensional constraint which depends upon not only the plate thickness but also the load and the material property.

Exist-null combination method for the topological optimization of plane continuum structure under multi-loading case with stress constraint;

Optimal Topology Design for Frame Structure of Semi-trailer under Stress Constraint;

To obtain the optimal design of membrane structures satisfying the stress constraints, according to the full stress criterion and the assumption of statically determined system, the thickness of membrane structures with stress constraints is optimized.
