Compressive Stress-Strain Relationships of Layered Solid Foams
Compressive Stress-Strain Relationships of Layered Solid Foams
This Demonstration calculates and plots the sigmoid compressive stress-strain curve of hypothetical slabs composed of three layers of solid foams having different mechanical properties and thicknesses. It also calculates and displays, separately, the individual components’ stress-strain curves. Each layer is characterized by the foam’s compressibility model equation, whose coefficients can be adjusted, and by its initial thickness, which also can be adjusted.
