In this paper, the crushing behavior of hexagonal honeycomb structures with finite boundaries (finite width and height) subjected to in-plane uniaxial compressive loading is studied based on the nonlinear finite element analysis. It is found that str

The equivalent in-plane elastic modulus [Formula: see text] of a honeycomb sandwich in the direction of cell vertical wall can be assessed by the law of mixture from the modulus of face sheet [Formula: see text] and the equivalent modulus of honeycom

In the present study, the evaluation technique of fracture loads for blunt U-shaped notches is investigated using two fracture criteria, i.e. the mean stress based line criterion and the volume-based strain energy density (SED) criterion, and Filippi

In this study, the problem of “what is the critical value of notch root radius ρ max below which the fracture load of the notch with ρ ≠ 0 can be evaluated by using the singular stress field for a sharp notch” is investigated analytically. Ba

In this study, a modified fracture criterion which satisfies the necessary stress and energy conditions is proposed for brittle materials. The criterion is based on the assumption that fracture is generated by the initiation of a crack with a finite

In this study, the failure behaviour of lattice sandwich panels under three-point loading has been studied using a nonlinear finite element analysis. The failure mechanisms of lattice-cored sandwich panels can be classified in three modes; facesheet

One of the authors has investigated the stress concentration in honeycomb core subjected to an uniaxial loading due to defect, in which some vertical cell walls are missing consecutively along one row. The objective of this paper is to extend the pre

In this paper, the estimation of maximum torsional moment for multicorner tubes under torsional loading was investigated using nonlinear FE analysis. The effects of tube geometries and strain-hardening coefficient on the torsional behaviour were disc
