Fracture Behavior of Two Biopolymers Containing Notches: Effects of Notch Tip Plasticity
Applied Sciences, 2020 This paper analyzes the notch effect on the fracture behavior of two biomaterials (a brittle bone cement and a ductile dental material) under mode I loading. U-notched Brazilian disk (UNBD) specimens of both materials were tested under remote compression,

Implications of Realistic Fracture Criteria on Crack Morphology
Frontiers in Physics, 2019 We study the effects realistic fracture criteria have on crack morphology obtained in numerical simulations with a stochastic discrete element method. Results are obtained with two criteria which are consistent with the theory of elasticity and compared ...
