TCL

Hi all,

I need to create a macro in Hypermesh with a TCL programming code. I have two problems. I've had the code yet, but It's written in Matlab code, I've heard that TCL can talk to Matlab by DDE. The second problem is that I don't know anything about TCL code. Anyone can help me, anyway?

 

Many thanks 

UEL CODES

Submitted by Filippo on
research

Hi all.

I'm Filippo, a new entry on imechenica community. I'm looking for a simple UEL code for Quad_2D-plane stress or plain strain.

Here's someone that can suggests manual or similar. 

I'm grateful in advance. 

swiching Nodal Result output to Integration Points in ANSYS

Submitted by saeedspace on
research

Hi every body

i modeled a plane with a notch with elastic-perfect plastic material. somewhere in model the stress reaches above the yield stress

so i think the reason is that ANSYS reports the nodal result output by default wish they interpolated from integration points results.

i want to see the integration points results but i dont know where to finde them.

Hi all

 

I am currently in my Master Degree in Civil Engineering . I am doing a research on concrete wrapped FRP sheets  with seismic loads and I want to do Finite Element Analysis using ANSYS. I already model concrete in ANSYS. Can anyone please help me  how to apply CYCLIC LOADS to the model.

and is it  necessary to make contact between different parts of solid element or not?

 

Awaiting the reply....

 

Help with curved specimen and mechanical loading

Submitted by tom_biomech on

Background:

Rib fractures in infants are highly suggestive of child abuse. I am performing mechanical testing and finite element analysis on pig ribs with the aim of characterising the behaviour of ribs under anterior-posterior (from end to end rather from the side) loading.

Large electric field induced strains in ferroelectric islands

Submitted by jzz108 on
research

An effective mechanism that generates large recoverable electric field induced strains in ferroelectric islands is studied by phase-field modeling. The large strains originate from the reversible 90° domain switching between a1 (a2) domains and c domains, driven by an applied electric field and an internal stress field. The electric field induced strains could be effectively controlled by the magnitude of island-substrate misfit and the aspect ratio of islands.

propper orthogonal decomposition

Model reduction based on Propper Orthogonal decomposition is widely used in Computational mechanics to reduce the number of degrees of freedom in systems. In the attached papers, we introduced a POD-based model reduction in a multiscale framework to significantly reduce the computations.
