本文提出了一项关于虚拟固化微结构的力学性能的研究，其中考虑了基质性能和纤维堆积的不确定性。使用商业程序ABAQUS并辅之以用户编写的子程序，使用有限元方法进行计算。采用制造过程中应力演化的瞬时线弹性模型来模拟固化过程。给出了不同尺寸固化微结构的横向刚度和强度的结果。并与不考虑固化残余应力的模型进行了比较。
This paper proposes a study on mechanical properties of virtually cured microstructures accounting for uncertainty in matrix properties and fiber packing. Computations are carried out using the finite element method (FEM) using the commercial code Abaqus supplemented by user written subroutines. An instantaneous linear elastic model for the stress evolution during manufacturing is employed to model curing. Results are presented in terms of transverse stiffness and strength for cured microstructures of different sizes. Comparisons are proposed with models not including curing induced residual stresses.
