基于Reddy逐层理论(Reddy’s Layerwise Theory
RLWT)和
O
(1)均匀化方法,建立了复合材料蜂窝夹芯结构的三尺度逐层多尺度分析方法(Layerwise Multiscale Analysis Method
LMAM),利用RLWT对复合材料层合板的宏观模型进行离散,采用三维有限元建立由纤维和基体组成的微观单胞模型。数值算例中,对含夹杂立方块体进行数值模拟,并与直接数值模拟(Direct Numerical Simulation
DNS)方法的模拟结果进行了对比,验证了LMAM方法的有效性。LMAM也被用于计算和分析复合材料蜂窝夹芯结构的宏观、介观和微观应力分布。
Based on Reddy’s layerwise theory (RLWT) and
O
(1) homogenization method
a three-scale layerwise multiscale analysis method (LMAM) for composite honeycomb sandwich structures was established. The macroscopic model of composite laminates was discretized by RLWT
and the microscopic unit cell model composed of fibers and matrix was established by three-dimensional finite element method. In the numerical example
the numerical simulation of the cubic block with inclusions was carried out
and the simulation results were compared with those of the direct numerical simulation (DNS) method
which verified the correctness of the LMAM. LMAM is also used to calculate and analyze the macroscopic
mesoscopic and microscopic stress distribution of composite honeycomb sandwich structures.
