Summary:The invention provides a stress-strain curve simulation method, which is used for acquiring a simulation stress-strain curve of a to-be-tested object clamped between a mass block and a test platform. The method comprises the following steps: acquiring a first acceleration curve and a second acceleration curve, capturing a part of the first acceleration curve in a time period to obtain a first effective curve, capturing a part of the second acceleration curve in the time period to obtain a second effective curve, obtaining a strain curve of the object to be measured according to the first effective curve and the second effective curve, and calculating a stress curve of the object to be measured based on the first effective curve and a contact area between the mass block and the object to be measured, and calculating a simulated stress-strain curve based on the strain curve of the object to be measured and the stress curve of the object to be measured by using an exponential equation, wherein the simulated stre
