Submitted by Laura De Lorenzis on

The Graduate School MUSIC offers its second Summer School at the Leibniz Universität Hannover from 8 to 12 September 2014.  This year's summer school on “Multiscale modeling of interfaces and advanced solution techniques" is hosted by the Institute of Continuum Mechanics

Co-simulation engine error,

I am operating a co-simulation analysis in Abaqus. This a kind of interaction between fluid and solid so I am doing co-execution. 
Unfortunately, when the program run up suddenly I encounter this error " 
 
Error in job Co-execution-3-Model-1: Co-Simulation error
Error in job Co-execution-3-Model-2: The partner program in the co-simulation has issued a fatal error message. This analysis will be terminated.

HELLO,

I want to know if carbon nanotubes reinforced composites are ductile as I want to do hydroforming process by using ABAQUS or any other metal forming process that can be implemented.

If it is formable than what are values of yeild strength, ultimate tensile strength, plastic strain,etc.

the matrix material is polymer(PmPV).

THANK YOU.

How to model fastener with same force-displacement behavior for all translational directions in a plane in Abaqus?

<p>Hi everyone. I want to model the fasteners connecting a wood sheathing to a steel frame in Abaqus. I want to input the same force-displacement behavior for all translational directions in the plane of the sheathing (like a radial spring). <br /> <br /> I was using spring element type Spring2 (nonlinear) but I could define behavior in only 2 translational directions in the sheathing plane (X and Z). This made my model overly stiff after the elastic range. I read about the RADIAL-THRUST connector element but it does not seem to be the one.

Contribution to dynamic behaviour of structures

Submitted by Adjal on

Most of topics here in this web site treat the physical behaviour of materials, I would like to share my knowledge and my ideas concerned the analysis vibration of materials ( forced and free) for understand the mechanical behaviour of structures

I adress this message to  researcher whom interssting on dynamic of  structures

Hello I am an undergraduate researcher working with a Split Hopkinson Pressure Bar and I'm new to this site. We recently changed from a set of 3/4" aluminum bars to a set of 1/2" aluminum bars and an interesting result occured. Our data collection system consists of a pair of strain gages midway along each bar.

Numerical analysis of quasi-static fracture in functionally graded materials

Submitted by Emilio Martíne… on

This work investigates the existing capabilities and limitations in numerical modeling of fracture problems in functionally graded materials (FGMs) by means of the well-known finite element code ABAQUS. Quasi-static crack initiation and growth in planar FGMs is evaluated. Computational results of fracture parameters are compared to experimental results and good agreement is obtained. The importance of the numerical fit of the elastic properties in the FE model is analyzed in depth by means of a sensitivity study and a novel method is presented.
