Phase‐Field Modeling of Fracture Under Compression and Confinement in Anisotropic Geomaterials

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 4, Page 1319-1335, March 2025.
ABSTRACT Strongly anisotropic geomaterials, such as layered shales, have been observed to undergo fracture under compressive loading. This paper applies a phase‐field fracture model to study this fracture process. While phase‐field fracture models have several advantages—primarily that the fracture path is not predetermined but arises naturally from ...

Recycling of Krylov Subspaces in the Simulation of Nonlinear Dynamic Systems

PAMM, Volume 25, Issue 1, March 2025.
ABSTRACT The paper deals with the implementation of a Krylov subspace recycling method into the solution of a nonlinear system of equations that arises during the time integration of the equations of motion of a hydrodynamically supported rotor system. The recycling BiCGStab algorithm is used in order to speed up the calculation.

Riemannian Shape Optimization of Thin Shells Using Isogeometric Analysis

PAMM, Volume 25, Issue 1, March 2025.
ABSTRACT In this contribution, we consider the optimal shape design of thin elastic shell structures based on a linearized shell model of Koiter's type, whose shape can be described by a surface immersed in three‐dimensional Euclidean space. We regard the set of unparametrized immersions of the surface as an infinite‐dimensional Riemannian shape space ...

A Trust‐Region Method for p‐Harmonic Shape Optimization

PAMM, Volume 25, Issue 1, March 2025.
ABSTRACT The appropriate scaling of deformation fields has a significant impact on the performance of shape optimization algorithms. We introduce a pointwise gradient constraint to an efficient algorithm for p$p$‐Laplace problems, while the complexity of the algorithm remains polynomial.
