Minimization of p-Laplacian via the Finite Element Method in MATLAB
Ctirad Matonoha, Alexej Moskovka, Jan Valdman
Minimization of energy functionals is based on a discretization by the finite element method and optimization by the trust-region method. A key tool is a local evaluation of the ap…
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…
Computational modeling of magnetic hysteresis with thermal effects
Martin Kružík, Jan Valdman
We study computational behavior of a mesoscopic model describing temperature/external magnetic field-driven evolution of magnetization. Due to nonconvex anisotropy energy describin…
Perfect plasticity with damage and healing at small strains, its modelling, analysis, and computer implementation
Tomáš Roubíček, Jan Valdman
The quasistatic, Prandtl-Reuss perfect plasticity at small strains is combined with a gradient, reversible (i.e. admitting healing) damage which influences both the elastic moduli…
Additive Schwarz preconditioner for the general finite volume element discretization of symmetric elliptic problems
Leszek Marcinkowski, Talal Rahman, Atle Loneland +1
A symmetric and a nonsymmetric variant of the additive Schwarz preconditioner are proposed for the solution of a nonsymmetric system of algebraic equations arising from a general f…
Max-min and min-max approximation problems for normal matrices revisited
Jörg Liesen, Petr Tichý
We give a new proof for an equality of certain max-min and min-max approximation problems involving normal matrices. The previously published proofs of this equality apply tools fr…
CANDECOMP/PARAFAC Decomposition of High-order Tensors Through Tensor Reshaping
Anh Huy Phan, Petr Tichavsky, Andrzej Cichocki
In general, algorithms for order-3 CANDECOMP/-PARAFAC (CP), also coined canonical polyadic decomposition (CPD), are easily to implement and can be extended to higher order CPD. Unf…
Low Complexity Damped Gauss-Newton Algorithms for CANDECOMP/PARAFAC
Anh Huy Phan, Petr Tichavský, Andrzej Cichocki
The damped Gauss-Newton (dGN) algorithm for CANDECOMP/PARAFAC (CP) decomposition can handle the challenges of collinearity of factors and different magnitudes of factors; neverthel…
A TFETI Domain Decomposition Solver for Elastoplastic Problems
M. Čermák, T. Kozubek, S. Sysala +1
We propose an algorithm for the efficient parallel implementation of elastoplastic problems with hardening based on the so-called TFETI (Total Finite Element Tearing and Interconne…
On Fast Computation of Gradients for CANDECOMP/PARAFAC Algorithms
Anh Huy Phan, Petr Tichavský, Andrzej Cichocki
Product between mode- unfolding $\bY_{(n)}$ of an -D tensor $\tY$ and Khatri-Rao products of factor matrices $\bA^{(m)}$, exists in algo…
