Fe thermomechanics and material sampling points [PDF]
The thermomechanics of finite elements of continuous media is discussed. The novel key concept introduced is that of material sampling points attributed to each finite element. Similar to representing the spatial interactions by a finite number of nodal quantities, the state of a finite element is represented by the set of local states at its sampling ...
