## XFEM

Hello,

As far as I understand from the previous blogs: we can now embed XFEM in ABAQUS. Is this approach restricted to linear elastic behavior? Can we simulate fracture propagation in an elasto-plastic material ("XFEM coupled with ABAQUS" type analysis) or is this approach only limited to fracture propagation in elastic materials.

Thanks,

Uno.

## FEM Analysis of Composite plate girder Bridge

hello friend,

my self jignesh patel, give some guide about the construction stage analysis of composite section.How to appy live load (movind load) in Construcion stage Analysis.

plz reply me if know abt the content.

thanks

Hi all!

I am trying to simulate the tensile test in ABAQUS. Could you please tell me how I can incorporate the power hardening stree strain relation in ABAQUS?

## What is the meaning and advantage of“ isoparametric element” in FEM？

Does the FEM software（ ANSYS，abaques，et al） ues the isoparametric element  concept?

## problem in full transient analysis

hi friends

i have problem in full transient analysis in ANSYS 11.0

kindly give me solution.

i have data .....

lenth=144 inch

area=120 sq inch

moment of inrtia=1000 inch rest to four

depth=10 inch

elastic modulas=3605 kips per sq inch

density of material=8.6805E-5  kips per cubic inch

FOR SOLUTION..(force 23.8 kips is linearly decreases from time = 0 to 0.042 at centre of the beam)

at time = 0 sec , force = -23.8 kips

Does anyone know of a simple book, approximately 50 pages or so, for plasticity?. I am looking for something that is similar to Morton Gurtin's "Topics in Finite Elasticty" published by SIAM. This book is an uncluttered treatment of finite deformation elasticity and was very useful for me during graduate work. I am NOT looking for 200-300 page texts, becasue I will never get around to reading them.

## 3D fracture analysis using Ansys

hi,

i m vijay doing M.TECH in aerospace,  i m doing project in the area of fracture mechanics using Ansys, so i need to find Energy release release rate for 3D plate (composite plate having cracks on thikness). i want material related to this, can anyone plz send the material.

## tutorial for hot deep drawing simulation

I  am  final  year  student  ,  doing  my project    on  "hot deep drwing  on  non-ferrous materials"  and    doing  simulation  on  abaqus . I  need  a  tutorial ,,,,,,,,,,,please   some  one  help

## K value calculation in Ansys

I am trying to calculate K values for a double tip crack orientated at 45 deg in a rectangular plate in ansys.I am stuck with a strange problem. When i give the Kcal command it says the crack face is not parallel to the active x axis. But i have checked the cordinates of the keypoints that i have used to create the crack. The crack is perfectly symetric about the active cordinate system  about the crack tip.Can somebody help me please.

## Abaqus/CAE version 6.6

Dear all,

For my final year project, I've done the 3D model of a test fixture which is used for the compression testing of a specimen.

When I apply a downward vertical displacement to top Slider B, eventually the 2-slider linkage mechanism will cause the bottom Slider A to move horizontally and to compress the cube shaped specimen.

## how can apply a tightening torque

I use the abaqus present , how can apply a tightening torque between an implant (screw) and the bone with abaqus......... thank you

## Central crack loaded with stress

Choose a channel featured in the header of iMechanica:

1. Central crack loaded with stress.

(A) The stress intensity factor for a central line crack in an infinite plate is found to be

K=p(πa)^.5

where p is the pressure exerted along the crack line. (A) Does this formula imply a stable or an unstable crack propagation when p reaches the critical stress level? (B)  Present an experiment to support your answer in (A). Specify your experiment in details.
