Compression Response of Composite Cushioning Materials in Series byn Virtual Parameter Methods

摘要

With the assumption that the constitutive relationship of every single cushioning layer is known in advance, this paper presents virtual parameter methods for predicting compressive responses of composite cushioning materials in series (i.e. multi-layered cushioning materials). In the proposed methods, a derivative term is introduced to transform nonlinear algebraic equations for characterizing compressive behaviours of the composite cushioning materials into explicit differential equations unde
