Individual materials are stored in the materials object. Each section inside the sections object should be identified by a unique positive integer.

Input Type Description
materials Object Each material is defined as an object with properties.

Material Properties Type Value Description
name String - The name of the material.
density Number Mass/Length3 The density of the material.
elasticity_modulus Number Pressure Modulus of elasticity of the material. Also known as Young's Modulus.
poissons_ratio Number - Poisson's Ratio, also known as coefficient of expansion.
