Y. Ezawa et N. Okamoto, DEVELOPMENT OF CONTACT STRESS-ANALYSIS PROGRAMS USING THE HYBRID METHOD OF FEM AND BEM, Computers & structures, 58(1), 1995, pp. 13-20
This paper deals with the development of two- and three-dimensional co
ntact stress analysis programs using a method combining the finite ele
ment method and the boundary element method. Designed to improve the a
ccuracy of analysis using the hybrid method, a new method for computin
g the equivalent stiffness matrix is described. Furthermore, the penal
ty function is applied to introduce the contact conditions, A three-no
de contact element was used for two-dimensional analysis and five-node
contact element, for three-dimensional analysis. Considering the appl
ication to general slide movements, a new eight-node contact element h
as been developed. The programs are applied to the problem of contact
between a magnetic disc and a slider. A thin-film of the disc and a sl
ider are modeled using finite elements. The substrate of the disc is m
odeled using boundary elements. Results confirm the validity and the a
ccuracy of this procedure.
