Finite element analysis of incrementally formed parts
Orientador(es)
Resumo(s)
Single point incremental forming (SPIF) processes represent a breakpoint from traditional forming processes, and possibly a new era in small batches production, customised parts or rapid prototyping.
Given its easy implementation, SPIF is being currently a subject of intensive experimental and numerical research. Consequently, dimensional inaccuracy in formed parts is still a real problem to tackle, demanding a correct prediction of forming forces, springback defects and strain path effects.
This work concerns a first step of a detailed numerical study, validated with available experimental results in the literature raised about simulation of SPIF processes. To this end, it is proposed a general simulation framework of SPIF processes using the finite element method with implicit solution schemes, along with innovative solid-shell elements for 3D analysis.
Finally, the use of solid-shell elements provides several advantages compared to shell elements, as considering automatically full 3D stress states and constitutive laws, thickness variations, double sided contact and normal stresses.
