## Line Spring elements errors

Choose a channel featured in the header of iMechanica:

Hello, All

***Problem ***

Failure pressure for Steam generator tube having 2 axial cracks. I am following one paper in that paper they found failure pressure by finding J and K values for line spring elements for different pressure. The pressure at which it approach material JIC(92N/mm) and KIC(65Mpa*sqrt(m)) value is considered as failure pressure or coalescence pressus

## Cellular Automata for Multi-scale Fracture

Could cellular automata be used to model mechanisms (for quasi-brittle fracture) that occur at the meso-scale and then feed these mechanisms to a macro-scale finite element model? Is it possible to replace constitutive models with mechanistic models, simulating mechanisms that lead to fracture instead of formulating equations that predict failure? These are typical questions that have motivated my recent collaboration with Dr Anton Shterenlikht at the University of Bristol.

Can anybody help me in using smeared crack and cohesive zone modeling in concrete for different grades. I was actually facing problem in using the same to identify fracture parameters of concrete using ABAQUS. I will also be helpful if anyone let me know about an alternate method to find fracture parameters of concrete using ABAQUS apart from using models. Thanks in advance.......
