Single point incremental forming simulation with adaptive remeshing technique using solid-shell elements

摘要

Numerical simulation of the single point incremental forming (SPIF) processes can bevery demanding and time consuming due to the constantly changing contact conditions between thetool and the sheet surface, as well as the nonlinear material behaviour combined with non-monotonicstrain paths. The purpose of this paper is to propose an adaptive remeshing technique implementedin the in-house implicit finite element code LAGAMINE, to reduce the simulation time. Thisremeshing technique automatically refines only a portion of the sheet mesh in vicinity of the tool,therefore following the tool motion. As a result, refined meshes are avoided and consequently thetotal CPU time can be drastically reduced.
