Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape. In a ...

Research in mechanics of solids mainly includes fundamental theory (elasticity, plasticity, variational principles, fatigue and fracture of materials and structures,and inelastic constitutive ...
