Molten lava and yogurt and are well-known examples of non-Newtonian fluids, also known as soft solids. A soft solid can act like either a solid or a liquid, based upon the stress that has acted upon ...

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

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 ...
