Flexible Linear Shaped Charge Modeling

Submitted by bdmmech on

Hi !!! all

I am doing the Hydrocode simulation using AUTODYN 2D Explicit Hydrodynamic Code. There is apoint of doubt in simulation of a 2D problem regarding the location of Detonation inside the explosive. In the case of a conical shaped charge it is very easy to assume the detonation at the apex of the cone but in case of FLSC being a linear cord and the initiation is done axially, it is very difficult to assume the same condition as that of conical shaped charge.

Please give me some useful solution.

Macro in Hypermesh TCL code and Matlab

Submitted by Nicholas Fantuzzi on
Choose a channel featured in the header of iMechanica

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

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

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....

 

Large electric field induced strains in ferroelectric islands

Submitted by jzz108 on

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.
