Geometric and material sensitivities for elasto‐plasticity including non‐local damage regularisation

Sensitivity analysis is applied to a regularised non-local ductile damage model. A variational approach utilised derive the analytical gradients of different objectives with respect either geometrical material parameters. Due definition model, enhanced algorithmic treatments are necessary capture its history dependent nature within sensitivity computation. The gradient information parameters used tolerant geometries in shape optimisation using Sequential Quadratic Programming (SQP). sensitivities analyse response and impact certain model during loading unloading specimen.
