An extended deep energy method for thermo-mechanical crack propagation

Han Zhang, Mehrisadat Makki Alamdari, Babak Shahbodagh +4

Thermo-mechanical fracture couples transient heat conduction on a cracked domain with a crack that grows as the temperature and the displacement evolve. Neural energy solvers have…

A mesh-free multiresolution deep energy method with phase-field modeling of brittle fracture

Han Zhang, Mehrisadat Makki Alamdari, Babak Shahbodagh +4

Phase-field modeling of brittle fracture removes the need to track cracks explicitly by recasting their evolution as the minimization of an energy functional. In return it requires…

Design of thermal meta-structures made of functionally graded materials using isogeometric density-based topology optimization

Chintan Jansari, Stéphane P. A. Bordas, Marco Montemurro +1

The thermal conductivity of Functionally Graded Materials (FGMs) can be efficiently designed through topology optimization to obtain thermal meta-structures that actively steer the…

Level set topology optimization of metamaterial-based heat manipulators using isogeometric analysis

Chintan Jansari, Stéphane P. A. Bordas, Elena Atroshchenko

We exploit level set topology optimization to find the optimal material distribution for metamaterial-based heat manipulators. The level set function, geometry, and solution field…

Adaptive shape optimization with NURBS designs and PHT-splines for solution approximation in time-harmonic acoustics

Javier Videla, Ahmed Mostafa Shaaban, Elena Atroshchenko

Geometry Independent Field approximaTion (GIFT) was proposed as a generalization of Isogeometric analysis (IGA), where different types of splines are used for the parameterization…

Adaptive Importance Sampling based Neural Network framework for Reliability and Sensitivity Prediction for Variable Stiffness Composite Laminates with hybrid uncertainties

Tittu Varghese Mathew, P Prajith, RO Ruiz +2

In this work, we propose to leverage the advantages of both the Artificial Neural Network (ANN) based Second Order Reliability Method (SORM) and Importance sampling to yield an Ada…

Weakening the tight coupling between geometry and simulation in isogeometric analysis: from sub- and super- geometric analysis to Geometry Independent Field approximaTion (GIFT)

Elena Atroshchenko, Gang Xu, Satyendra Tomar +1

This paper presents an approach to generalize the concept of isogeometric analysis (IGA) by allowing different spaces for parameterization of the computational domain and for appro…

A new one point quadrature rule over arbitrary star convex polygon/polyhedron

Sundararajan Natarajan, Amrita Francis, Elena Atroshchenko +1

The Linear Smoothing (LS) scheme \cite{francisa.ortiz-bernardin2017} ameliorates linear and quadratic approximations over convex polytopes by employing a three-point integration sc…
