Equilibrium equations

Infinitesimal parallelepiped in static equilibrium

A solid body is in static equilibrium when the resultant force and moment on each axis is equal to zero. This can be expressed by the equilibrium equations. Continue reading

Index notation for tensors and vectors

Right handed Cartesian coordinate system

Index notation is used extensively in literature when dealing with stresses, strains and constitutive equations. The reason is that it reduces drastically the number of terms in an equation and simplifies the expressions. Continue reading
