Nonlinear Johnson Cook Material Constitutive Model For High Speed Impact Using Finite Element Analysis

---

This thesis (or dissertation) focuses on the application and modification of the Johnson-Cook (J-C) constitutive material model for analyzing materials subjected to high-speed impact and large deformations, typically encountered in fields like ballistics or armor protection. The J-C model is a widely used semi-empirical model that describes the material's flow stress as a function of plastic strain, strain rate, and temperature. The study specifically utilizes the Finite Element Analysis (FEA) method to simulate the dynamic impact process. The research aims to modify and calibrate the nonlinear J-C parameters based on experimental data to accurately predict the deformation and failure behavior of the material under extreme thermomechanical conditions.
