J-INTEGRAL EVALUATION IN MIXED-MODE I/II COMPACT TENSION SHEAR (CTS) SPECIMENS
Last modified: 2008-06-15
Abstract
In this paper, Finite Element (FE) simulations have been performed in order to assess the most suitable
J-integral estimation method for the mixed-mode I/II CTS specimens. Several analytical formulas for the J
calculation have been examined and compared to the FE results and a suitable solution has been
identified. Finally, a specific plastic h factor, hpl, for the above-mentioned specimen has been proposed
and the mixed-mode J-R curves of a ductile steel evaluated.
