Summary: This paper establishes an elastic-plastic damage constitutive model for 3D tubular braided composites with defects, considering plastic effects and damage accumulation. The sequential trans-scale analysis method is used to establish 3D tubular braided composite models with defects. The elastic and elastic-plastic damage models of the fiber and the matrix are established based on the brittleness of the fiber or yarn and the plasticity of the matrix. An interface element is also established to characterize the mechanical properties of the interface with the tractor-separation constitutive model. The finite element results of the axial compression properties of 3D tubular braided composites are in good agreement with the experimental results, considering porosity and plasticity of the matrix, longitudinal shear nonlinearity of the yarn, and bilinear constitutive relationship of the interface.

Summary: Thanks to the 2D braiding manufacturing method, the hybrid braided composite composed of the biaxial and unidirectional layers can be mass-produced. The effects of hybridization structures on the damage characteristics and energy absorption capacity of braided composite tubes under axial compression were investigated. It was found that the easily progressed intra-laminar cracks in unidirectional layers promoted splitting damage feature, leading to enhanced energy absorption capacities in hybrid tubes than pure biaxial braided tube. In particular, the UBU tube had significantly higher energy absorption per unit area compared to the BBB tube.

Summary: A homogenization method is proposed for the vibration analysis of periodic sandwich panels. Periodic boundary conditions are applied to a representative volume element (RVE) and the complex stiffness matrix of the sandwich panels is obtained through direct-solution steady-state dynamic analysis (DSDA) using the finite element method (FEM) in the frequency domain. The natural frequencies, mode shapes, and loss factors of the structures are obtained using shell models based on equivalent single-layer (ESL) theory and finite element-modal strain energy (FE-MSE) method. Pyramidal lattice truss sandwich panels made of carbon fiber reinforced plastics (CFRP) are used to validate the effectiveness of the homogenization method, and the results are compared with experiments and solid models. The effects of the number of cells and damping layers are discussed.
