Study of Distortion in Composite Plate Using Different Boundary Conditions

Abstract

Use of the composite material is increased in past few year as it gives improved characteristics of material which is not possible in conventional material. Many different industries wants to use this material for their product as it proves better than regular material. There are many scopes ahead in this field as it is still a developing area for research. Here, as attempt has been made to determine distortion of simply supported symmetrically 4-ply laminated composite plate subject to uniformly distributed load. The classical lamination theory has been used for calculating the deflection of the plate and a code has been generated using SCILAB. The finite element had been carried out using ANSYS 14.5 to determine deflection for the same and results were compared. The effects of fiber orientation of 4-ply composite pate on deflection have been investigated using FE analysis for same boundary condition. The effects of fiber orientation for boundary condition clamped on all sides have also been studied. All these analysis have also been carried out using another FE software Hyper Works and results are compared with analytical as well as ANSYS solution. The experimental set up has been prepared and composite plates have been made by using manual lay-up method. For fiberglass composite plate, deformation has been found for simply supported boundary condition with uniformly distributed loading condition by experiment. The results for the same have been compared with FE analysis results.
