Delayed acceptance sampling with Hamiltonian proposal subchains for random field materials inference

Simona Bérešová, Michal Béreš, Tomáš Luber +1

This paper focuses on accelerating Markov chain Monte Carlo sampling in Bayesian inverse problems in which forward model evaluations dominate the computational cost. It builds on s…

Convex optimization problems inspired by geotechnical stability analysis

Stanislav Sysala, Michal Béreš, Simona Bérešová +3

This paper is motivated by the limit load, limit analysis and shear strength reduction methods, which are commonly employed in geotechnical stability analysis or similar applicatio…

Optimization and variational principles for the shear strength reduction method

Stanislav Sysala, Eva Hrubešová, Zdeněk Michalec +1

This paper is focused on the definition, analysis and numerical solution of a new optimization variant (OPT) of the shear strength reduction (SSR) problem with applications to slop…

An abstract inf-sup problem inspired by limit analysis in perfect plasticity and related applications

Stanislav Sysala, Jaroslav Haslinger, Daya Reddy +1

This work is concerned with an abstract inf-sup problem generated by a bilinear Lagrangian and convex constraints. We study the conditions that guarantee no gap between the inf-sup…

Bounds on the elastic threshold for problems of dissipative strain-gradient plasticity

B. D. Reddy, S. Sysala

This work is concerned with the purely dissipative version of a well-established model of rate-independent strain-gradient plasticity. In the conventional theory of plasticity the…

Efficient and flexible MATLAB implementation of 2D and 3D elastoplastic problems

Martin Čermák, Stanislav Sysala, Jan Valdman

We propose an effective and flexible way to implement 2D and 3D elastoplastic problems in MATLAB using fully vectorized codes. Our technique is applied to a broad class of the prob…
