TL;DR: In this article, the robust design of structures with stochastic parameters is studied using optimization techniques and the robustness of the feasibility is also taken into account by involving the variability of the structural response in the constraints.

TL;DR: In this paper, the robust design of non-linear structures with path-dependent response is stated as a two-criteria optimization problem and is solved by the method of mathematical programming, where the perturbation technique is applied in conjunction with the incremental loading procedure for the response moment analysis of pathdependent nonlinear structural systems with random parameters.

TL;DR: In this paper, the Lagrangean description of the viscous melt in the drops, as constrained by surface tension and the developing contact with the target, has been coupled to an analysis of transient thermal phenomena accounting also for the solidification of the material.

TL;DR: In this article, the perturbation-based stochastic finite element analysis and robust design optimization of deformation processes of inelastic solids are addressed, and an iteration scheme based on the secant system operator is given for the solution of the perturbed equations in case that a tangent matrix is not available.

TL;DR: In this paper, methods of analysis and design for inelastic deformation processes with random input parameters are exposed and tasks concerning process design are defined and the employment of the stochastic analysis techniques for exploring the parameter space as well as for design improvement and optimization.
