abstract

fiber metal laminates (fmls) are new composite materials consisting of thin metal layers and high strength composite layers. arall (aramid aluminum laminate) is a family of the fml that consists of thin aluminum sheets along with kevlar/epoxy composite layers. this material has many advantages such as light weight, excellent corrosion, fatigue and impact resistance. since, arall is a new material, therefore presentation of a model for nonlinear behavior analysis is important. this paper presents the elastic– plastic behavior of arall under in- plane tensile loading. for this purpose, the orthotropic plasticity theory and modified classical laminated plate theory are used. in the orthotropic plasticity model, a three parameter plastic potential function is used. in the second theory, the kevlar/epoxy composite layers and aluminum sheets are assumed to be linearly elastic and orthotropic elastic– plastic solids, respectively. good agreement is obtained between results of two models. the results show that the case study behavior is almost bilinear under tensile loading and it has more strength in longitudinal direction in comparison to transverse direction. variation of the poisson’s ratio is considered in longitudinal and transverse loading too.

Simulation of Foaming and Deformation for Composite Aluminum Foams

In this study, at the first stage, the rupture criterion of bubbles wall in Aluminum metal foam liquid was investigated by using Lattice Boltzmann. The two phases modeling were accomplished by using a modified Shan-Chen model. This model was run for several bubbles in A356+3wt.%SiC melt system. Then, bubbles morphologies (virtual metallographic) for A356+3wt.%SiC foams were simulated. Results s...

Elastic deformation of composite cylinders with cylindrically orthotropic layers

This paper provides explicit analytical expressions for displacement and stress fields in a multilayered composite cylinder with cylindrically orthotropic layers subjected to homogeneous boundary conditions. The solutions are derived in the assumption of perfect bonding between layers. The components of displacement, strain and stress are expressed in terms of the integration constants found fr...

Nonlocal DQM for a Nonlinear Buckling Analysis of DLGSs Integrated with Zno Piezoelectric Layers

The nonlocal nonlinear buckling of a double layer graphene sheet (DLGS) covered by zinc oxide (ZnO) piezoelectric layers is investigated in this study. The surrounding circumstances of the system are considered as a Pasternak foundation including spring constants and a shear layer. Graphene sheets are subjected to longitudinal magnetic field and biaxial forces. On the other hand, the ZnO piezoe...

Nonlinear Vibration Analysis of the Composite Cable using Perturbation Method and the Green-Lagrangian Nonlinear Strain

In this study, nonlinear vibration of a composite cable is investigated by considering nonlinear stress-strain relations. The composite cable is composed of an aluminum wire as reinforcement and a rubber coating as matrix. The nonlinear governing equations of motion are derived about to an initial curve and based on the fundamentals of continuum mechanics and the nonlinear Green-Lagrangian stra...
