Accurate simulation of delamination with a resin-rich layer-dependent penalty stiffness based on structural cohesive elements
Xiaopeng Ai, Christos Kassapoglou, Boyang Chen
Shell-based cohesive elements tend to overestimate the compression ahead of the crack tip because of approximations in the penalty stiffness. In this study, the higher-order struct…
A new approach for the determination of through-thickness and free-edge stresses in composite laminates based on structural elements
Xiaopeng Ai, Christos Kassapoglou, Boyang Chen
The paper introduces a method that uses structural cohesive elements with a penalty stiffness derived from resin‑rich layers to recover out‑of‑plane stresses in thin‑shell models o…
Autoregressive Modelling and Synthetic Generation of High-Fidelity, Statistically Equivalent 3D Microstructures for As-Manufactured Misalignments in Fiber-Reinforced Composites
Mohamad A. Raja, Clemens Dransfeld, Boyang Chen
This study presents an integrated framework for processing, modelling, and generating statistically representative three-dimensional fiber microstructures from experimental X-ray-$…
Solving 1D Poisson problem with a Variational Quantum Linear Solver
Giorgio Tosti Balducci, Boyang Chen, Matthias Möller +1
Different hybrid quantum-classical algorithms have recently been developed as a near-term way to solve linear systems of equations on quantum devices. However, the focus has so far…
Predicting Open-Hole Laminates Failure Using Support Vector Machines With Classical and Quantum Kernels
Giorgio Tosti Balducci, Boyang Chen, Matthias Möller +2
Modeling open hole failure of composites is a complex task, consisting in a highly nonlinear response with interacting failure modes. Numerical modeling of this phenomenon has trad…
Structural cohesive element for the modelling of delamination in composite laminates without the cohesive zone limit
Xiaopeng Ai, Boyang Chen, Christos Kassapoglou
Delamination is a critical mode of failure that occurs between plies in a composite laminate. The cohesive element, developed based on the cohesive zone model, is widely used for m…
