Hi guys, I'm trying to develop a USDFLD subroutine for a coupled thermal-electrical analysis. The goal of the subroutine is to determinate the decomposition grade as a function of the temperature of a composite. It seems to be easy but I am having some problems.
The grade of decomposition...
Hi guys, I'm having problems with the introduction of a electrical load type of surface current. I want to recreate the arc channel of a lightning strike over a composite plate. The arc has a 10mm diameter, and the magnitude of the lightning strike is 40kA with a certain...
Hi guys, I'm trying to run a lightning strike simulation over a curve composite plate. I've done a previous simulation over a composite planar plate and I obtained good results.
The thing is, when I introduce the same boundary conditions, load and material as the planar plate in the curve...
Hi guys, I'm trying to refine my mesh in the center of my 3D-plate model as a cross (I upload an image as example). I want to know if exist any option to make the mesh smaller as it approximates to the center and grow as it gets away to the edges.
My method was divide the model in sets and use...
Hi,I have some doubts introducing the latent heat data. I'm trying to introduce the latent decomposition heat of a fiber/epoxy that is assumed to be 4.8x10^3 kJ/kg and is released between 300 ºC and 500 ºC. A linear rate of decomposition is assumed in the decomposition temperature range. And a...
Hi, I'm trying to do a subroutine that works as follow: I want to introduce a temperature limit condition to each element of my model. If the element reach a temperature value, I want to change its electrical conductivity properties. (I'm doing a Coupled thermal-electrical analysis)
Which type...
Hi guys, I'm intending to carry out a simulation of an lightning impact over a compoiste plate using Abaqus (Coupled thermal-electrical analysis). First of all I put here the finite element model and boundary conditions:
-Specimen has 100mm width and 150mm lenght. Thickness of 4mm.
- Composite...
