| Summary: | (DMA). DMA, although proven as a method to quickly accounted for by using a Taylor series expansion on the and accurately determine linear material properties, and recovery tests, the data provide more detail and characterization lack the ability to rapidly characterizations. Creep and recovery tests have been characterize nonlinear viscoelastic materials. A characterized by the experimental procedure developed correlated to an experimental procedure which is has not been extended for use of nonlinear here which uses DMA to identify nonlinear material herein and is used as a validation of the nonlinear DMA information. The proposed method implements a dynamic introduced as a tool for nonlinear viscoelastic material characterization. Thin film polyethylene is material properties is Dynamic Mechanical Analysis mean stress of the nonlinear viscoelastic model. These method of rapidly identifying linear viscoelastic nonlinear material properties, however, these tests are or oscillatory input in Schapery's nonlinear properties are identified using DMA, but, like creep properties. The technique utilizes the speed in which the most widely used procedures for characterizing theoretical developments for nonlinear DMA are theory. time consuming and tedious. An approach is presented Traditional methods of viscoelastic material viscoelastic model. This oscillatory input is |
