a) Johnson-Cook (JC) – for metals at high strain rate

Strength Properties:

Defines the yield surface and how a material resists plastic (permanent) deformation under stress. The "Steinberg-Guinan" or "Steinberg-Lund" models are frequently cited for calculating shear modulus and yield strength as functions of pressure, temperature, and strain rate. Key Materials Covered

1. Core Distinction: EOS vs. Strength

The combination of a robust equation of state and a validated strength model is essential for predicting material behavior under extreme dynamic loading. Selected materials illustrate the diversity of responses:

is a foundational technical report authored by at the Lawrence Livermore National Laboratory (LLNL) . Originally published in 1991 (UCRL-MA-106439) and updated in 1996, it serves as a critical reference for hydrocode simulations—software used to model high-velocity impacts and shock wave physics.
