ABSTRACT
A new analysis scheme for the two-dimensional elastostatic contact problems is proposed
in this paper. Principal objective is to promote high computational efficiency for the
above-mentioned problem, specifically for the unknowns boundary identification
corresponding to a variety of contact phases including separation. Two elastic bodies
are treated individually by the new formulation similar to the flexibility method, and
are coupled to satisfy the conditions specified on the contact region, which is oriented
to make fit for parallel computation. The scheme can reduce recomputation of system
matrices for each iteration stage and their modification is sufficient of only small part
for the assumed contact region. Some numerical examples are shown for the cases
with and without friction.
