Laminated composites, a contemporary material, are widely used as a roofing option in civil engineering. They have benefits such as a lower weight-to-strength ratio, durability to harsh weather, and customizing options. However, researchers have expressed concern about the restricted transverse shear capacity, which can result in delamination under extreme strain, which is often confined inside the layers and eventually causes collapse. To overcome this, cylindrical shells are typically supplied with stiffeners to withstand static pressure deformation. There is a dearth of extensive research on the behaviour of laminated composite stiffened cylindrical shells under static loads in the existing literature. The purpose of the study is to investigate the behaviour of laminated composite stiffened cylindrical shells in terms of total deformation, maximum principal stress, and maximum principal strain caused by static pressure. On both simply supported and clamped two-ply laminated cylindrical shells, various stiffener sites are investigated. The stacking sequences are changed to compare the parameters mentioned. This study conducts a parametric investigation to draw engineering-relevant conclusions using ANSYS. According to the study's conclusion, the inclusion of differentially organized stiffeners results in a reduction in deformation, stress, and strain levels.

“…Jing et al [ 28 ] optimized the stacking sequence for the composite plates in order to maximize the critical buckling and damage load. On the other hand, Cho [ 29 ] maximized the buckling load and damage resistance for the composite shell optimizing the fiber orientations. From the optimization results, it has been observed that the buckling performance increased from 28.9% to 48.6% according to the load conditions, and from 22.2% to 50.6% according to the damage conditions.…”

Hydraulic cylinders are used in many different areas from aviation to construction machinery and are generally manufactured using conventional steels that stand out with their low strength to weight ratio. In this study, it was aimed to design a hydraulic cylinder using composite materials to reduce cylinder weight. In this context, a novel composite hydraulic cylinder was designed, and numerical analyses for the composite portions of the hydraulic cylinder were carried out. For the numerical model, an aluminium liner and cylinder heads with the geodesic dome profiles were used, and composite layers were formed on their surfaces by using the Ansys ACP module. In the numerical

“…They considered both elastic and rigid supports, and it was found that GA's performance was better as compared to other optimization tools. Cho [8] used GA to optimize the design of a composite cylindrical shell which is most prone to buckling and failure on application of axial load, torsional load, or both. It was found that the GA optimized shell design possessed better mechanical properties as regards to conventional ones.…”

This paper presents a smart crack detection system using genetic algorithm (GA) for a cantilever beam. The accuracy of prediction is optimized by performing parametric optimization of the first three natural frequencies. The three modes of natural frequencies are obtained from the experimental procedures and are optimized to reduce the percentage of error in predicting the relative crack position and crack depth from a fixed position. Comparison of analytical method is in agreement with the experimental values as the error percent between the experimental and predicted values is below 10%.
