A discussion upon the sensitivity of the mk model to input data
Source abstract
Abstract
An aluminum sheet, AA5182, is modeled (as rigid-plastic) with two yield criteria that, for all practical purposes, generate almost identical yield surfaces for this alloy. Yet, the differences between the two in limit strain prediction using the MK model are noticeable, pointing to a hyper-sensitivity of the MK model to the input data. It is shown that this sensitivity is intrinsic to the MK model and not of numerical nature.
