Abstract
Highlights •Explicit form of elasticity of three cubic lattices is derived by the singum model.•Two types of bond potentials are considered for cellular and granular materials.•The numerical simulation verifies the exactness of the formulation.•The configurational stress caused by prestress changes the effective elasticity.•Zero thermal expansion coefficient and positive temperature derivative of elastic modulus are achieved.
