FEA Calculations

FEA is a numerical method for predicting the deformation of a part. Essentially, the part is broken down into a number of discrete entities or elements. A simultaneous analysis is performed on each individual element and the effect an element has on the neighboring elements, abaqus™, a commercially available finite element analysis (FEA) software program,[45] was used for the modeling. FEA calculations were carried out to simulate the deformation of the edge seal for IGUs exposed to temperatures of -30°C (-22°F) and +60°C (+140°F). IGUs with galvanized steel and aluminum spacers were modeled with DOW CORNING 982 as the secondary sealant; units with stainless steel spacer were modeled with DOW CORNING 3-0117 sealant.
