Bayesian inversion for unified ductile phase-field fracture

A Bayesian inversion framework for ductile fracture is developed to provide accurate knowledge regarding the effective mechanical parameters and synthetic and experimental observations are used to estimate the posterior density of the unknowns.

An Orthotropic Elastic-Plastic Constitutive Model for Masonry Walls

The use of a continuum structural model for the analysis of masonry structures in the plane stress state and validation of the model after its implementation in a proprietary finite element method (FEM) system via user-supplied subroutine is discussed.

Influence of Moisture Content and Wet Environment on the Fatigue Behaviour of High-Strength Concrete

The influence of a wet environment on the fatigue behaviour of high-strength concrete has become more important in recent years with the expansion of offshore wind energy systems. According to the

Intake System Performance Stability as a Function of Flow Throttling

This paper presents a numerical analysis of the stability of the flow parameters along the intake duct of an aircraft jet turbine engine. This problem has been investigated by many research teams and

Bayesian Inversion with Open-Source Codes for Various One-Dimensional Model Problems in Computational Mechanics

This study employs Bayesian inversion for several mechanical problems and studies its applicability to enhance the model accuracy, and develops a developed package written in MATLAB that provides useful information about mechanical model problems and the backward BayesianInversion setting.

Computational performance studies for space-time phase-field fracture optimal control problems

The optimal control solution algorithm is a Newton algorithm, which is obtained with the reduced approach by eliminating the state constraint, that deals with the state, adjoint, tangent, and adjoint Hessian equations.

A comparative review of peridynamics and phase-field models for engineering fracture mechanics

Computational modeling of the initiation and propagation of complex fracture is central to the discipline of engineering fracture mechanics. This review focuses on two promising approaches:



Phase-field modeling through iterative splitting of hydraulic fractures in a poroelastic medium

We study the propagation of hydraulic fractures using the fixed stress splitting method. The phase field approach is applied and we study the mechanics step involving displacement and phase field

A Bayesian estimation method for variational phase-field fracture problems

This work proposes a parameter estimation framework for fracture propagation problems with focus on uncertainties arising in the solid material parameters and the critical energy release rate and a Bayesian approach.

Phase‐field modeling and simulation of fracture in brittle materials with strongly anisotropic surface energy

Crack propagation in brittle materials with anisotropic surface energy is important in applications involving single crystals, extruded polymers, or geological and organic materials. Furthermore,

Bayesian inversion for steady flow in fractured porous media with contact on fractures and hydro-mechanical coupling

In this paper, the implementation of the Bayesian inversion is realized via Metropolis-Hastings Markov chain Monte Carlo approach and the sampling procedure uses the delayed acceptance of samples based on a surrogate model which is constructed during a preliminary sampling process.

A Phase-Field Method for Propagating Fluid-Filled Fractures Coupled to a Surrounding Porous Medium

The pressurized phase- field framework is extended to fluid-filled fractures in which the pressure is computed from a generalized parabolic diffraction problem, and the phase-field variable is used as an indicator function to combine reservoir and fracture pressure.
