Modeling centerline damage with DEFORM®

摘要

The DEFORM~® metalworking modeling system can be applied to the development of centerline damage,rnby way of the Cockcroft and Latham workability criterion, and this paper summarizes such recent work atrnRensselaer. Near-centerline flow in the absence and presence of an inclusion has been modeled, andrncomparisons have been made to Cockcroft and Latham projections from tensile testing. Beyond this,rnshear strain modeling has been undertaken, both for shear strains at the "equator" of spherical inclusionsrnand for chevron-shaped shear strain fields.
