“…This “butterfly” pattern is a well-known phenomenon for both composite and metal plates with a center hole undergoing uniaxial tension. 23–27 At locations further away from the hole, there was a uniform low-level stress distribution. Peak stresses were always located on the left and right sides of the hole, reaching 73.5 MPa (at 1000 N), 147 MPa (at 2000 N), and 220.5 MPa (at 3000 N).…”

This is the first study, to the authors' knowledge, to simultaneously perform a direct comparison of finite element analysis, strain gage measurements, and infrared thermography for stress analysis under both static and dynamics tensile loads of the classic geometry of a composite plate with a center hole. The plate was made from a carbon fiber-reinforced epoxy composite with dimensions of 250 mm length × 25 mm width × 2.2 mm thickness and a 5 mm diameter center hole. Using static tensile loads of 1000 N, 2000 N, and 3000 N, the plate Von Mises stress field was evaluated using strain gages versus finite element analysis. Using cyclic tensile loads of 1000 N and 1600 N at 5 Hz, the plate Von Mises stress field was assessed using strain gages versus infrared thermography. The strain gages versus finite element analysis line-of-best-fit showed poor agreement (slope = 2.1, R = 0.81), although the slope could easily be applied as a correction factor when comparing the two methods. The strain gages versus infrared thermography showed much better agreement (slope = 0.95, R = 0.91). Finite element analysis displayed a “butterfly” stress field around the hole with peaks of 73.5 MPa (at 1000 N), 147 MPa (at 2000 N), and 220.5 MPa (at 3000 N). Infrared thermography showed a “ring” of high stress around the hole with peaks of 74.8 MPa (at 1000 N) and 102.9 MPa (at 1600 N). All three methods showed similar relative trends for the carbon fiber-reinforced epoxy plate.

“…The magnitude of both normal and shear stress is observed to be higher for linear analysis compared to nonlinear analysis, so for an optimum design of the nonlinear analysis structure is essential. Abdul Siddique shaik1 et al [33] have done stress analysis around the circular hole, made up of different materials using ANSYS software. The rectangular plate with a central hole is analyzed using carbon epoxy with different fiber angles such as 0 0 , 30 0 , 45 0 , 60 0 , 90 0 and the better fiber angle was found to determine the stress concentration.…”

A composite material is generally a combination of materials differing in composition or form on a macro scale for the purposes of attaining specific characteristics and properties. The developments in the field of composite materials have granted significant weight reduction in structural design. When compared to metallic materials, composites offer many advantages, especially high strength, stiffness to weight ratio, excellent fatigue properties, and corrosion resistance. Plates, curved panels, the cylindrical shell-shaped forms of models are being broadly used in many structural packages of engineering structure. For design the structure, it is important to know the behaviour of these under static, free vibration, buckling condition. The present paper aims to review the literature on static, free vibration, and buckling analysis of composite flat panel, curved panel, and cylindrical shell. Further, the testing procedure of laminate, design guidelines of laminates and cost estimations with mechanical properties comparison of laminate with metal, CLT (classical lamination theory) basis including thermal and moisture expansion for stiffness evaluation are also summarised in this paper.

“…Using finite element method as a basis the determination of Von misses and deflection for a rectangular plate with elliptical home was carried out by Dheeraj and Singh [6].With the plate dimensions remaining the same and varying the diameter of the hole to the width of the plate the effect on orientation angle on shear, axial stresses and their corresponding deflections for the clamped free boundary conditions are examined. Shaik and Mirzana [7] performed the static analysis for a plate with a central hole with different materials. Mekalke [8] investigated the stress analysis of a plate with a central hole subjected to uniform stress distribution.…”

The geometric irregularities present inside a structure results in an improper stress distribution caused during manufacturing, which not only affects the strength of the component but also its vibrational behaviour when operated in a fluctuating environment. The emphasis of this paper is to evaluate the stress behavioral characteristics of plates with different cutout shapes. Two different loading conditions with three different types of plates made of Mild Steel are used for this analysis. From the present investigation, it may be concluded that where the max stress occurs. The methodology adopted in this research work is based on the numerical technique of finite element method, which uses SOLID 185 in ANSYS 19.1 solver. For further analysis, the obtained results are validated with previous literature works which were found satisfactory when related to the present study. It may be noted that FEM provides good insight for the determination of stress and deflection, with different parameters.
