Stress Analysis of Perforated Plate Under Uniaxial Compression Using Experimental Stress Analysis and Finite Element Analysis
The perforated plate element constitutes essential structural components in many structures, such as ship grilling, plate, box girders of bridges, hulls, dock gates, platforms of offshore structure and structures used in aerospace industries. In this work, a rectangular plate of size 200 × 200 mm as shown in Fig. 1 having a circular hole in laminar and turbulent pattern with hole dia. 17 mm has been selected. The same plate was modeled in CATIA V5 & the model of the plate is imported in ANSYS 14 for shear stress analysis. The shear stress developed in the plate under the load of 70 Kg is 0.4377 N/mm.
In Experimentation plate of advanced material, Epoxy resin was used. The pattern of the hole was changed from turbulent to laminar. The loading and boundary condition applied for were kept the same in experimentation and modeling. The minimum shear stress found to be 0.2972 N/mm2 for 4 × 4 laminar hole pattern in the epoxy plate. The comparison of maximum shear stress is decreasing as a hole pattern changes from turbulent to laminar.
To validate the maximum shear stresses of a plate consisting laminar hole structure experimental setup was developed. To conduct the experimental work, using the selected boundary condition circular polar scope is used, and the load is applied stepwise from 10 Kg to 70 Kg. In experimental analysis maximum shear stress value is formed to be 0.2850 N/mm2 for Epoxy resin plate in laminar hole pattern.
