The perforated plate element constitute very important structural components in many structures, such as ship grilling, hulls, dock gates, plate, box girders of brides, platforms of offshore structure and used in aerospace industries. In this project work we have select a rectangular plate having a circular hole in 4×4 pattern with hole dia. 17mm. The same plate was created in CATIA V5 & the model of plate is import in ANSYS 14 for shear stress analysis. The shear stress developed in plate under the load of 70 Kg is 0.4377 N/mm2. In development phase we create a new plate of advanced material Epoxy resin. The pattern of the hole also changes from turbulent to laminar [4*4]. The same loading and boundary condition applied for the newly formed plate as for the existed plate. The final results came for these plate are 0.2972 N/mm2. The comparison between results of existed plate & newly formed plate shows the shear stresses goes on decreasing in newly formed plate. To validate the results of newly formed plate we create on experimental setup using the selected boundary condition to conduct the experimental work we use circular polariscope and apply load stepwise up to 70 Kg. In experimental analysis we get stress value of 0.2850 N/mm2 for Epoxy resin plate.
