Embodiment 1
[0103] Take the three-dimensional laminated structure as an example;
[0104] The dynamic analysis method of above-mentioned material structure, comprises the following steps:
[0105] (1) Extract geometric parameters, material parameters and boundary parameters of each sub-layer of the three-dimensional laminated structure: the geometric parameters include the length, width and height of each sub-layer; the material parameters include the density, modulus of elasticity, Poisson's ratio and ply angle; the boundary parameters include fixed support, simply support or free;
[0106] (2) Utilize three-dimensional elasticity theory, construct sub-layer geometric equation, physical equation and equation of motion according to the parameter extracted in described step (1): described sub-layer geometric equation is the geometric equation of strain-displacement relation; Sub-layer physical equation is the physical equation of the stress-strain relationship;
[0107] (3) according to ...
