Continuum models of ductile fracture : A review
The past 20 years have seen substantial work on the modeling of ductile damage and fracture. Several factors explain this interest. (i) There is a growing demand to provide tools which allow to increase the efficiency of structures (reduce weight, increase service temperature or load, etc.) while keeping or increasing safety. This goal is indeed first achieved by using better materials but also...
متن کاملEffect of Constraint on Ductile Crack Growth and Ductile-Brittle Fracture Transition of a carbon Steel
Ductile-brittle fracture transition was investigated using compact tension (CT) specimens from -70 o C to 40 o C for a carbon steel. Large deformation finite element analysis has been carried out to simulate the stable crack growth in the compact tension (CT, a/W=0.6), three point-point bend (SE(B), a/W=0.1) and centre-cracked tension (M(T), a/W=0.5) specimens. Experimental crack tip opening di...
متن کاملThe unstable occult cervical spine fracture: a review.
The initial evaluation and management of cervical spine injuries is of critical importance because of the impact of early treatment and management on the patient's eventual outcome. The devastation and cost of missing even one unstable cervical spine fracture is tremendous. The existence of patients with an unsuspected cervical spine fracture who have few, if any, symptoms and/or signs of an in...

متن کاملMeshfree simulations of thermo-mechanical ductile fracture
In this work, a meshfree method is used to simulate thermo-mechanical ductile fracture under finite deformation. A Galerkin meshfree formulation incorporating the Johnson-Cook damage model is implemented in numerical computations. We are interested in the simulation of thermomechanical effects on ductile fracture under large scale yielding. A rate form adiabatic split is proposed in the constit...
