Multistage Sheet Metal Forming with Intermediate Annealing: Comparison of Finite Element Simulations with Experiments 1999-01-1560
This paper describes a methodology to simulate multistage sheet metal forming with intermediate heat treatments and its application to the three stage forming of an engine nacelle inlet lip. This capability has been validated by comparing results of finite element simulations for plastic strains at various points in the sheet with values obtained experimentally using the strain circle technique.
