Reduced order computation of 2D elastodynamic Green's functions in layered soil using a low-rank tensor approximation
Zainab Farooq, Amar Pashov, Pieter Reumers +2
The evaluation of elastodynamic Green's functions across numerous source-receiver locations, frequencies, and material properties, particularly in the context of parametric studies…
Multi-temporal decomposition for elastoplastic ratcheting solids
Jacinto Ulloa, Geert Degrande, José E. Andrade +1
This paper presents a multi-temporal formulation for simulating elastoplastic solids under cyclic loading. We leverage the proper generalized decomposition (PGD) to decompose the d…
A micromechanics-based variational phase-field model for fracture in geomaterials with brittle-tensile and compressive-ductile behavior
Jacinto Ulloa, Jef Wambacq, Roberto Alessi +3
This paper presents a framework for modeling failure in quasi-brittle geomaterials under different loading conditions. A micromechanics-based model is proposed in which the field v…
Bayesian inversion for unified ductile phase-field fracture
Nima Noii, Amirreza Khodadadian, Jacinto Ulloa +4
The prediction of crack initiation and propagation in ductile failure processes are challenging tasks for the design and fabrication of metallic materials and structures on a large…
Interior-point methods for the phase-field approach to brittle and ductile fracture
Jef Wambacq, Jacinto Ulloa, Geert Lombaert +1
The governing equations of the variational approach to brittle and ductile fracture emerge from the minimization of a non-convex energy functional subject to irreversibility constr…
On the Selection of Random Field Evaluation Points in the p-MLQMC Method
Philippe Blondeel, Pieterjan Robbe, Stijn François +2
Engineering problems are often characterized by significant uncertainty in their material parameters. A typical example coming from geotechnical engineering is the slope stability…
Phase-field modeling of fatigue coupled to cyclic plasticity in an energetic formulation
Jacinto Ulloa, Jef Wambacq, Roberto Alessi +2
This paper presents a modeling framework to describe the driving mechanisms of cyclic failure in brittle and ductile materials, including cyclic plasticity and fatigue crack growth…
