Comparing experimental fracture properties and micromechanical (or global-local/multiscale) finite element simulations

global-local

I am interested in developing a global-local finite element model (micro/macro) to simulate flexural testing of a composite material. Flexural loading will be applied on global model (macro) and crack propagation will be simulated in the local model (micro). I want to compare stress intensity factor or any other fracture property obtained from local model (micro) with that of experimental results.

I would appreciate if anyone could suggest some references/literature in this area. Any kind of suggestions would be great!

Microplane modeling of shape memory alloy tubes under tension, torsion, and proportional tension–torsion loading

Submitted by R.Mehrabi on

Shape memory alloy
constitutive modeling
proportional loading

In this paper, a phenomenological constitutive
model based on microplane model is used to simulate tension, torsion and proportional tension-torsion on NiTi thin-walled tube. Validation of the
microplane model against experimental results in different loading conditions demonstrates
the capability of this approach.
This publication will benefit the numerical and experimental study on SMAs.

Hello all,

I am interested in using a finite element software in a supercomputer setting (i.e. bluegene, cray, etc.). Does anyone have experience running finite element solutions on massively parallel supercomputers? What solvers are most amenable to such a task?

We are delighted to announce the publication of the first papers in Case Studies in Fire Safety. Case Studies in Fire Safety provides an open forum for the rapid publication of short, structured case studies in fire safety and related short communications providing an essential compendium of case studies for fire protection engineers, designers, researchers and other practitioners in the field of fire safety.

Transient Dynamic Analysis of Clamped Clamped Laminated Cylindrical Shell

Transient Dynamic Laminated Shell

Dear friends,

I am trying to find thife transient dynamics response of clamped clamped laminated cylindrical shell subjected to Radial impulsive load. I am getting very irregular response using Newmark Integration scheme. But, using HHT-alpha method, high frequency noise from the response gets removed, but damping is intrdoced (Numerical Damping). Although i have not introduced and damping in my model. How to overcome this problem.

I need help in this regard.

Hi I need a help if anyone can solve my problem please help me out. I want to use the output file of the result as a input file in ABAQUS i.e, if a apply tensile load to a model it will elongate and I need the elongated model as a input file for carrying out the next step. If anyone can pl send me the .jnl file or .inp or .cae file. I am using ABAQUS/STANDARD VERSION 6.8
