#Plasticity #fracture

Dear Friends and Colleagues:

The Fourth International Conference on Damage Mechanics, ICDM4, will be held at Louisiana State University in Baton Rouge, Louisiana, on May 15th-18th, 2023. The abstract submission will be due on December 15th, 2022. Please consider submitting an abstract using the templates (https://lnkd.in/gBEW8SKq). If you submitted an abstract in 2019, you would need to resubmit it before the deadline.
Best wishes to you all!

Dear iMechanicians,

I hope that the following paper is of interest to you. We use for the first time Gurtin (2004) gradient plasticity theory to investigate crack tip mechanics, revealing the existence of an elastic core adjacent to the crack tip, resembling a dislocation-free zone. Also, we show that the combination of strain gradient hardening and dislocation blockage can rationalise brittle fracture in elastic-plastic material interfaces.
