Second, a removal algorithm is proposed by introducing an image inpainting algorithm to this field and adding an illumination constraint.

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.
