Response tailoring of elasto-plastic trusses

Wallin, Mathias LU ; Watts, Seth ; Sigmund, Ole and Tortorelli, Daniel (2025) In Structural and Multidisciplinary Optimization 68(4).
Abstract

In this work we tailor the response of trusses loaded beyond their yield limit. The truss structures are modeled using finite strain theory and rate-independent elasto-plasticity. We design trusses with a tailored mechanical response that is between “elastic” and “elastic-ideal-plastic” subject to the volume constraint. The design updates are generated by the gradient-based Method of Moving Asymptotes (MMA) solver and the sensitivities of the response functions are computed using a path-dependent adjoint sensitivity analysis. The computations are performed in Matlab.
