A Constraint Model for Interface Stress Element Method without Virtual Elements

Abstract:

Article Preview

The traditional constraint model employed in Interface Stress Element Method is cumbersome due to the using of additional virtual elements. To remedy this, a new constraint model without virtual elements was proposed, based on the introductions of constrained interface, formula for stress mode on bound boundary and governing equations considering geometric boundary conditions. With the elimination of virtual elements, constraints can be treated more naturally and simply. Programs based on this model were developed and numerical examples were provided to demonstrate the validity and convenience of the presented technique.
