Abstract

Machining processes or other processes in which material failure is induced present a unique class of benchmark problems for computational solid mechanics methods and constitutive models. The data available from these problems include force vs. time measurements, failure plane orientations, residual stress measurements at the failed surfaces, and geometric information about machined chips.
