ABAQUS Release Notes  


9.1 Distributed surface tractions and edge loads

Products: ABAQUS/Standard  ABAQUS/Explicit  ABAQUS/CAE  

Benefits: General or shear surface tractions can be applied as element-based or surface-based distributed loads. Distributed edge tractions (general, shear, normal, or transverse) and edge moments can be applied to shell elements as element-based or surface-based distributed loads.

Description: General surface tractions allow you to specify a traction, , acting on a surface, , in an arbitrary direction. The resultant load, , is computed by integrating over :

You can also specify a shear surface traction that acts tangent to a surface .

General edge tractions allow you to specify a distributed edge load, , acting on a shell edge, , in an arbitrary direction. The resultant load, , is computed by integrating over :

You can also specify distributed edge tractions that act in directions tangent, normal, or transverse to a shell edge and distributed edge moments that always act about a shell edge.

General surface tractions and general edge tractions can be specified to be follower or non-follower loads. Shear surface tractions and all other edge tractions are modeled as follower loads.
