LY 564/Ara 2954 Strain Simulations Using LS-DYNA

Finite Element Analysis of Strain Rate-Dependent Behavior of Araldite LY 564 with Aradur 2954 Using LS-DYNA
Project Description:
This project involves modeling the strain rate-dependent mechanical behavior of Araldite LY 564 with Aradur 2954, produced by HUNTSMAN Corp., using LS-DYNA finite element software.
We have experimental data for a strain rate of 0.01/s. Based on these results, the material properties will be defined in LS-DYNA and the simulation will be calibrated to match the experimental data as closely as possible.
After the base model is validated at 0.01/s, simulations will be performed at 0.1/s and 0.001/s by only changing the strain rate parameter. Experimental data for these two additional strain rates are also available, but will be used only for validation—not for input or calibration.
Provided Resources:
A detailed research report of the material’s experimental characterization
Experimental data for strain rates of 0.01/s, 0.1/s, and 0.001/s
A required format/template for reporting and presenting the results (including layout and graphical style)
Deliverables:
Selection and definition of an appropriate material model in LS-DYNA
Simulation of the material behavior at 0.01/s and calibration to match experimental results
Simulations at 0.1/s and 0.001/s for comparison
A report comparing simulation outputs with experimental data, assessing accuracy and consistency
Preferred Qualifications:
Proven experience with LS-DYNA
Strong knowledge of material modeling and calibration
Familiarity with polymers or composite material behavior under varying strain rates
Proficiency in finite element analysis and post-processing of simulation data
