VALIDATION OF A NONLINEAR 2-DIMENSIONAL INTERFACE ELEMENT FOR FINITE-ELEMENT ANALYSIS

Nonlinear interface elements are currently used to represent nonbonded interfaces such as bone/implant and turbine blade/disk interfaces in finite-element analyses, The accuracy of the two-dimensional interface element of ANSYS was verified by comparing the finite-element solutio n of a problem involving a nonbonded interface with the analytical sol ution. Then, photoelastic tests were conducted in order to validate th e finite-element solutions in problems similar in geometry to a specif ic bone/dental implant system, It was concluded that the two-dimension al interface element of ANSYS can be used with confidence.
