The Equation of State (EOS) and strength properties are fundamental concepts in materials science that describe how substances respond to external forces and environmental changes. While an EOS defines a material's fluidic or volumetric behavior (pressure-volume-temperature relationship), strength models describe its resistance to deformation and the limits at which it yields or fails. 1. Fundamentals of Equation of State (EOS)
$$Y(P, E) = Y_0 f(\epsilon) (1 + \alpha P) (1 - \beta E)$$ equation of state and strength properties of selected
The Johnson-Cook strength model (empirical, rate- and temperature-sensitive) is often used: [ \sigma_y = [A + B\varepsilon^n][1 + C \ln\dot\varepsilon^*][1 - T^*m] ] The Equation of State (EOS) and strength properties
