A hyperelastic extended Kirchhoff–Love shell model with out-of-plane normal stress: II. An isogeometric discretization method for incompressible materials Comput. Mech. (IF 4.1) Pub Date : 2024-04-04
Abstract This is Part II of a multipart article on a hyperelastic extended Kirchhoff–Love shell model with out-of-plane normal stress. We introduce an isogeometric discretization method for incompressible materials and present test computations. Accounting for the out-of-plane normal stress distribution in the out-of-plane direction affects the accuracy in calculating the deformed-configuration out-of-plane

A novel smoothed particle hydrodynamics method for multi-physics simulation of laser powder bed fusion Comput. Mech. (IF 4.1) Pub Date : 2024-04-04 Yibo Ma, Xu Zhou, Fan Zhang, Christian Weißenfels, Moubin Liu
In this work, we propose an efficient smoothed particle hydrodynamics (SPH) method for simulating laser powder bed fusion (LPBF). The multi-physics process of LPBF, including the heat transfer and phase change with complex boundaries, is accurately resolved by a novel heat source model and a modified continuous surface force based on a corrected surface delta function. Moreover, we also develop an

Variational three-field reduced order modeling for nearly incompressible materials Comput. Mech. (IF 4.1) Pub Date : 2024-04-01 Muhammad Babar Shamim, Stephan Wulfinghoff
This study presents an innovative approach for developing a reduced-order model (ROM) tailored specifically for nearly incompressible materials at large deformations. The formulation relies on a three-field variational approach to capture the behavior of these materials. To construct the ROM, the full-scale model is initially solved using the finite element method (FEM), with snapshots of the displacement

A numerical framework based on localizing gradient damage methodology for high cycle fatigue crack growth simulations Comput. Mech. (IF 4.1) Pub Date : 2024-02-12
Abstract Standard non-local gradient damage methodology for fatigue analysis has an intrinsic drawback of unusual widening of the damage zone. This causes a rapid growth of crack in the simulations which often violate experimental evidences. In order to tackle this undesirable behaviour, the localizing gradient damage methodology has been formulated for high cycle fatigue crack growth simulations.

Abstract A recent mixed formulation of the Virtual Element Method in 2D elastostatics, based on the Hu-Washizu variational principle, is here extended to 2D elastodynamics. The independent modeling of the strain field, allowed by the mixed formulation, is exploited to derive first order quadrilateral Virtual Elements (VEs) not requiring a stabilization (namely, self-stabilized VEs), in contrast to
