Advanced adhesives foster hybrid structures
in the automotive industry is the increasing use of metal/plastic hybrid structures. They incorporate metal-reinforcing members strategically attached to a plastic framework, combining the structural integrity of metal with the net shape and weight-to-stiffness advantages of fiberfilled plastics. The resulting

RIM goes bumper to bumper
and body panels. Placing long-glass fibers in RIM parts such as this truck's cargo box make them suitable for structural components. Encapsulating long-fiber inserts in RIM parts make them suitable for structural applications such as this tailgate. RIM parts can have highquality surface finishes

Guidelines for NONLINEAR ANALYSES
, such as Cosmos-DesignStar, loading comes from adding forces in small increments, such as onetenth of a pressure value at a time, and then updating the stiffness of the model at each step. Linear-static analysis, on the other hand, assumes that induced displacements are small, changes in structural stiffness caused

A better way to design high-performance structures
. For instance, its unformatted inputs means users need not supply a CAD model. The dimensions typed into the Start Menu, actually an Excel spreadsheet, give enough information to get things started. Users are also asked to supply edge conditions, external loads, needed safety factors, structural
