Quasi‐static and dynamic compressive properties of three soybean oil‐based polymeric materials, which were made through the reaction of epoxidized soybean oil with diamine compounds, have been determined. Quasi‐static properties were determined with an MTS 810 hydraulically driven testing machine, whereas dynamic experiments were conducted with a split Hopkinson pressure bar (SHPB) modified for low‐impedance material testing. All three materials were capable of deforming to very large strains, with significant nonlinear stress–strain response. Their compressive behaviors were strain‐rate sensitive with distinctive rate sensitivities. On the basis of the experimental results at various strain rates, a compressive one‐dimensional stress–strain material model with strain‐rate effects was developed to describe the experimental results for all three materials under both quasi‐static and dynamic loading conditions. © 2005 Wiley Periodicals, Inc.
