| description | The invention provides a method and a system for calculating stress-strain response of an engineering structure, and relates to the technical field of engineering structure analysis, linear interpolation is carried out on temperature by using material parameters, and the stress-strain of the engineering structure in a complex temperature field can be calculated by using a small number of groups of material parameters; meanwhile, an error control strategy is combined in an explicit integration scheme, it can be guaranteed that when the constitutive model is used for structural stress-strain calculation, the calculation speed, convergence and calculation errors can be considered at the same time, a program does not need to divide extremely small increment steps, whether errors meet requirements or not is judged through an error control module, and the calculation efficiency is improved. If the error does not meet the requirement, the step length of the increment step is automatically reduced, calculation is res |
