School of Light Industry, Harbin University of Commerce, Harbin 150028, China) Abstract The paper has analyzed the dynamic and static data of plant straw texture compound material. The cushioning characteristic of the compound package material has been gotten. With the S-F constitutive frame, the static compression model and nonlinear dynamic compression model have been built considering material density, shape function, strain ect. Experiments have been done and the parameters of the model were successful to identify. The results of experiments show the constitutive model had a good fitness in the parameters of model. The research has provided important principle for the cushioning material package design and further study on cushioning property of plant straw texture material.
