Library case Y622: Thermal expansion of composite solid block.

This case, which is loaded from PLANT library, deals with the calculations of the displacements and stresses in uniformly heated block composed of the materials of different mechanical properties.

It is used here as an example of extensive processing the calculation results with the aim to get the distribution of normal and shear stresses by the numerical differentiation of displacement field.

The outcome is the stress fields which may be viewed by PHOTON. The use file for the latter is supplied.

The PLANT statements placed in Q1, below the headings "OUTPUT INFORMATION", mainly use the indicial operations. Besides, PLANT is used to initialise some fields and to introduce the displacement boundary conditions.
