Modelling non-linear aeroelastic loads in long-span bridges with extreme learning machines
Gledson Rodrigo Tondo, Samir Chawdhury, Sergio Andres Castro Giraldo +1
Accurate modelling of aerodynamic loads is essential for predicting instabilities and ensuring the safety of long-span bridges. A methodology is introduced for modelling aerodynami…
A Memory Efficient Adjoint Method to Enable Billion Parameter Optimization on a Single GPU in Dynamic Problems
Leon Herrmann, Tim Bürchner, László Kudela +1
Dynamic optimization is currently limited by sensitivity computations that require information from full forward and adjoint wave fields. Since the forward and adjoint solutions ar…
Generalized eigenvalue stabilization for immersed explicit dynamics
Tim Bürchner, Lars Radtke, Sascha Eisenträger +4
Explicit time integration for immersed finite element discretizations severely suffers from the influence of poorly cut elements. In this contribution, we propose a generalized eig…
A CFL condition for the finite cell method
Tim Bürchner, Lars Radtke, Philipp Kopp
Immersed boundary finite element methods allow the user to bypass the potentially troublesome task of boundary-conforming mesh generation. When combined with explicit time integrat…
On the efficiency of explicit and semi-explicit immersed boundary finite element methods for wave propagation problems
Tim Bürchner, Lars Radtke, Philipp Kopp +3
Immersed boundary methods have attracted substantial interest in the last decades due to their potential for computations involving complex geometries. Often these cannot be effici…
Quantitative Comparison of the Total Focusing Method, Reverse Time Migration, and Full Waveform Inversion for Ultrasonic Imaging
Tim Bürchner, Simon Schmid, Lukas Bergbreiter +3
Phased array ultrasound is a widely used technique in non-destructive testing. Using piezoelectric elements as both sources and receivers provides a significant gain in information…
CAD-compatible structural shape optimization with a movable Bézier tetrahedral mesh
Jorge López, Cosmin Anitescu, Timon Rabczuk
This paper presents the development of a complete CAD-compatible framework for structural shape optimization in 3D. The boundaries of the domain are described using NURBS while the…
The Discontinuous Strain Method: accurately representing fatigue and failure
Leon Herrmann, Alireza Daneshyar, Stefan Kollmannsberger
Fatigue simulation requires accurate modeling of unloading and reloading. However, classical ductile damage models treat deformations after complete failure as irrecoverable -- whi…
Implicit-Explicit Time Integration for the Immersed Wave Equation
Christian Faßbender, Tim Bürchner, Philipp Kopp +2
Immersed boundary methods simplify mesh generation by embedding the domain of interest into an extended domain that is easy to mesh, introducing the challenge of dealing with cells…
Phase field method for quasi-static hydro-fracture in porous media under stress boundary condition considering the effect of initial stress field
Shuwei Zhou, Xiaoying Zhuang, Timon Rabczuk
Phase field model (PFM) is an efficient fracture modeling method and has high potential for hydraulic fracturing (HF). However, the current PFMs in HF do not consider well the effe…
A surrogate model for computational homogenization of elastostatics at finite strain using the HDMR-based neural network approximator
Vien Minh Nguyen-Thanh, Lu Trong Khiem Nguyen, Timon Rabczuk +1
We propose a surrogate model for two-scale computational homogenization of elastostatics at finite strains. The macroscopic constitutive law is made numerically available via an ex…
Phase field modeling of quasi-static and dynamic crack propagation: COMSOL implementation and case studies
Shuwei Zhou, Timon Rabczuk, Xiaoying Zhuang
The phase-field model (PFM) represents the crack geometry in a diffusive way without introducing sharp discontinuities. This feature enables PFM to effectively model crack propagat…
A NURBS-based Inverse Analysis for Reconstruction of Nonlinear Deformations of Thin Shell Structures
N. Vu-Bac, T. X. Duong, T. Lahmer +4
This article presents original work combining a NURBS-based inverse analysis with both kinematic and constitutive nonlinearities to recover the applied loads and deformations of th…
A Virtual Element Method for 2D linear elastic fracture analysis
Vien Minh Nguyen-Thanh, Xiaoying Zhuang, Hung Nguyen-Xuan +2
This paper presents the Virtual Element Method (VEM) for the modeling of crack propagation in 2D within the context of linear elastic fracture mechanics (LEFM). By exploiting the a…
