Boundary Stress
Use the Boundary Stress node to define the total surface (boundary) stress through a stress tensor, a traction force, or a pressure. Add this node from the Mechanical submenu. The stress condition reads
where σp is a symmetric stress tensor, the product σpn defines a traction force. The traction condition reads
where Ftr is the surface traction force. The pressure condition reads
where pbnd is the pressure applied to the boundary (acting in the normal direction).
Stress
Select a Stress typeStress tensor, Traction (the default), or Pressure. For Stress tensor enter the (symmetric) Stress tensor σp (SI unit: N/m2) components, for Traction enter the traction force Ftr (SI unit: N/m2) components, and for Pressure enter the boundary pressure pbnd (SI unit: Pa).
