Curing process simulation in Abaqus | HETVAL, UMAT, USDFLD, DISP, UEXPAN

This video tackles the crucial yet challenging topic of curing simulation for fiber-reinforced composites (FRC).  We'll explore how to leverage Abaqus software to optimize curing processes and achieve top-quality FRC products.

Optimizing the curing process can be a balancing act - ensuring quality while maintaining production efficiency.  This video showcases how numerical simulations in Abaqus can be a game-changer:
✅Predicting Temperature Profiles: Accurately model heat flow within the composite during curing, considering the heat released by chemical reactions.
✅Analyzing Stress & Strain: Identify potential stress and strain concentrations that can compromise the final product.
✅Optimizing Curing Cycles: Use simulation results to adjust temperature and pressure profiles for optimal curing.

To do this simulation correctly in the Abaqus, several subroutines are needed.
Several??!!!🤯🤯🤯🤯 Do not wory!! We'll make it easy for you to understand this; here is the list of subroutines and their tasks:
⚡USDFLD: to calculate the degree of cure, and its derivative with respect to time.
⚡UEXPAN: to consider the nonmechanical strains.
⚡UMAT: to evaluate the residual stress within the laminate layers.
⚡HETVAL: to apply the internal heat generation.
⚡DISP: to apply curing temprature protocol.

In this video, first you will learn what is the Curing process in fiber-reinforced composites. 🤔🤔
Next, Thermo-chemical simulation of curing process in FRCs.
After that, Thermo-chemo-mechanical analysis of curing.
You will learn all in this video.🧐🧐

You will see an example, a simulation of this complocated process in this video. BUT, you can have more plus an article that is explain more about this crucial process in composite production:
