TL;DR: Tangent operators and design sensitivities for transient non-linear coupled problems were derived in this article for finite element implementations with history dependent response and rate-independent elastoplasticity.

TL;DR: In this article, an incremental, direct differentiation method for design sensitivity analysis of structures with rate-independent elastoplastic behavior is presented, which can be evaluated with only a modest increase in computational expense beyond the cost of simulation.

TL;DR: In this paper, a new incremental direct differentiation method for design sensitivity analysis of structures with history-dependent material response is presented, which uses the domain parameterization approach to represent design shape variations, and the consistent tangent operator to ensure that the sensitivity estimate is consistent with the underlying simulation model.

TL;DR: The definition of a general purpose control scheme for steering synthetic vision‐based agents and the proposition of cost functions for evaluating the perceived danger of the current situation are introduced.

TL;DR: In this article, a systematic approach for the design of weakly coupled thermoelastoplastic systems is presented, where the Newton-Raphson iteration method is used in the solution process so that analytic design sensitivity formulations may be efficiently derived via the direct differentiation technique.
