Finite Element Simulation of Interlaminar and Intralaminar Damage in Laminated ...
Soroush,M.; Fard,K. Malekzadeh; Shahravi,M.Abstract Here In this study, the composite laminates subjected to transverse impact with consideration interlaminar and intralaminar damage based on Cohesive Zone Model (CZM) and Progressive Damage Model (PDM) are investigated by numerical analysis using ABAQUS commercial finite element code. The delamination in stacking ply with the same fiber orientation is considered as interlaminar damage and the delaminati...
Vibration Analysis of a Cylindrical Sandwich Panel with Flexible Core Using an ...
Pourmoayed,A.R.; Fard,K. Malekzadeh; Shahravi,M.Abstract This paper deals with free vibration analysis of thick cylindrical composite sandwich panels with simply supported boundary conditions based on a new improved higher-order sandwich panel theory. The formulation used the third-order polynomial description for the displacement fields of thick composite face sheets and for the displacement fields in the core layer based on the displacement field of Frosti...
High Order Impact Elastic Analysis of Circular Thick Cylindrical Sandwich Panel...
Fard,K. Malekzadeh; Ghorghabad,A. Veisi; Azarnia,A. H.; Ghasemi,Faramarz AshenaiAbstract This study dealt with the dynamic model of composite cylindrical sandwich panels with flexible cores and simply supported boundary conditions under low velocity impacts of multiple large or small masses using a new improved higher order sandwich panel theory (IHSAPT). In-plane stresses were considered for the core and face sheets. Formulation was based on the first order shear deformation theory for th...

Fard,K. Malekzadeh; Livani,M.; veisi,A.; Gholami,M.For the first time, the bending analysis of a double curved sandwich panel was presented which was subjected to point load, uniform distributed load on a patch, and harmonic distributed loads and was based on a new improved higher order sandwich panel theory. Since the cross-sectional warping was accurately modeled by this theory, it did not require any shear correction factor. Also, the present analysis incorp...

Fard,K. Malekzadeh; Livani,M.; Ghasemi,Faramarz AshenaiThis paper dealt with free vibration analysis of thick double curved composite sandwich panels with simply supported or fully clamped boundary conditions based on a new improved higher order sandwich panel theory. The formulation used the first order shear deformation theory for composite face sheets and polynomial description for the displacement field in the core layer which was based on the displacement fiel...
