Review on the prediction of residual stress in welded steel components [PDF]
, 2020 Residual stress after welding has negative effects on the service life of welded steel components or structures. This work reviews three most commonly used methods for predicting residual stress, namely, empirical, semi-empirical and process simulation ...

Multimesh finite element methods: Solving PDEs on multiple intersecting meshes [PDF]
Computer Methods in Applied Mechanics and Engineering, 2018 We present a new framework for expressing finite element methods on multiple intersecting meshes: multimesh finite element methods. The framework enables the use of separate meshes to discretize parts of a computational domain that are naturally separate;

New methodology for calculating damage variables evolution in Plastic Damage Model for RC structures [PDF]
, 2017 The behavior of reinforced concrete (RC) structures under severe demands, as strong ground motions, is highly complex; this is mainly due to joint operation of concrete and steel, with several coupled failure modes.

Stabilized material point methods for coupled large deformation and fluid flow in porous materials
, 2019 The material point method (MPM) has been increasingly used for the simulation of large deformation processes in fluid-infiltrated porous materials. For undrained poromechanical problems, however, standard MPMs are numerically unstable because they use ...

Self-supporting structure design in additive manufacturing through explicit topology optimization
, 2017 One of the challenging issues in additive manufacturing (AM) oriented topology optimization is how to design structures that are self-supportive in a manufacture process without introducing additional supporting materials. In the present contribution, it
