Boundary conditions


Boundary conditions consist of prescription of displacement and of stress. The boundary S of the body van be divided into two parts, Su and St. The boundary conditions (BC's) are described as:

formula_16             on Su



formula_17         on St




in which tx and ty are traction forces (stresses on the boundary) and the barred quantities are those with known values.
