 Scan&Solve can display all general stress components.  Checking the component stresses can be a way to verify that the correct boundary conditions were applied to the model.  Viewing the individual stress components can also provide insight on the cause of a high danger level in a particular region. Scan&Solve can display all general stress components.  Checking the component stresses can be a way to verify that the correct boundary conditions were applied to the model.  Viewing the individual stress components can also provide insight on the cause of a high danger level in a particular region.

 Scan&Solve computes the component stresses from the calculated displacements using linear elasticity.  The stresses are oriented to the model's global coordinate system. Scan&Solve computes the component stresses from the calculated displacements using linear elasticity.  The stresses are oriented to the model's global coordinate system.

 The first letter of the stress component refers to the face of the element the stress is acting on, and the second letters refers to the direction of action. For example, Stress XY refers to the shear stress acting in the Y direction on the X face of the element. Stress XX is the normal stress acting on the X face in the X direction, and can be referred to as just Stress X. The first letter of the stress component refers to the face of the element the stress is acting on, and the second letters refers to the direction of action.

 This load case illustrates Scan&Solve's display of the normal stress component Stress XX.  The X element face is loaded with a 1 N distributed force, which corresponds to an axial tensile stress of 1 Pa.  The opposite X element face is restrained in the X, Y, and Z directions. This load case illustrates Scan&Solve's display of the normal stress component Stress XX.  The X element face is loaded with a 1 N distributed force, which corresponds to an axial tensile stress of 1 Pa.  The opposite X element face is restrained in the X, Y, and Z directions.

 Shear stresses act parallel to the corresponding face of the differential stress element.  The static equilibrium loading for an element loaded only in Shear XY and YX is shown below. A 1 N force is applied parallel to each face, which creates a 1 Pa shear stress in the directions shown. Shear stresses act parallel to the corresponding face of the differential stress element.  The static equilibrium loading for an element loaded only in Shear XY and YX is shown below.
