To obtain static stress-strain curves of the Calcium plastic structure by using universal testing machine, the calcium-plastic corrugated cardboard composite structure static constitutive model was established adopting the vertical impact test. Upon dynamic impact test new method , stress - strain curve is obtained through the input and output acceleration pulse using two accelerometers integrating acceleration signals twice .Finally the stress - strain curve of calcium-plastic corrugated cardboard composite structure under the excitation of the half sine pulse is determined.
