MSC.Software, the leader in multidiscipline simulation ( solutions that accelerate product innovation, today announced that McMaster University is gaining excellent results with Marc simulation software for the advanced nonlinear analysis of stable unbonded-fiber reinforced elastomeric isolator (SU-FREI) bearings.

Fiber reinforced elastomeric isolators include alternating bonded layers of rubber and fiber reinforcement. Finite element analysis (FEA) of a SU-FREI demands advanced engineering simulation software capable of addressing incompressibility, large deformation, and large strain of the rubber layers, and simulation of contact boundary conditions of the isolator.

Participants involved in the McMaster SU-FREI research program say that the Marc nonlinear software ( product from MSC.Software has unique features which allow them to develop and proof test an analytical model for a complex seismic isolator. The complexity of the isolator includes nonlinear properties with initial softening and subsequent hardening of the multi-layered unit (associated with its stability), very large deformations for efficient seismic mitigation, and ongoing loss of contact on some surfaces with development of contact on other surfaces (associated with its unbonded nature).

"The Marc nonlinear simulation software has unique features that allow us to solve a complex problem in a very timely manner," said Mike Tait, Professor at McMaster University. "A unique advantage of Marc is its automatic global remeshing capability which is very effective and more user-friendly compared to many other commercially available advanced FE-software solutions. We have achieved excellent correlation with results of physical tests on the bearings."

"We are pleased to see the research team at McMaster utilizing the advanced nonlinear capabilities of Marc," said David Yuen, VP of Americas Sales at MSC.Software. "This effort represents another great example of an exciting project underway in the area of advanced engineering analysis at the research level, and MSC.Software is thrilled to be collaborating in such efforts."
