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.

“…The composite materials investigation in previous years in different applications was due to the high strength to weight ratio; therefore, this investigation for composite materials being modified for mechanical properties for composite materials by reinforcement with different fibers, and then modified for composite by reinforcement with varying concentrations of powder, [1][2][3]. Then, the investigated different composite materials structures are as a beam, plate, and other facilities with various applications, such as the vibration of the plate with different parameters, [4][5], buckling for a plate with multiple parameters, [6][7][8], stress analysis for other structures, fatigue characterization with different applications, [9], and prosthetic and orthotics structures. Thus, due to the impartment for composite materials and application, then it was necessary to investigate the modification of the composite materials with reinforcement by nanoparticle materials since this modification with the composite materials leads to an increase in the material mechanical properties with a high value and with a low increasing for the weight of the material, [10][11].…”

Previous research presented the effect of nanomaterials on the mechanical properties of composite materials with various volume fraction effects; in addition, their research presented the effect of nanomaterials on the same mechanical characteristics for a composite plate structure, such as vibration and thermal buckling behavior. Therefore, since the use of shell structures is for large applications, it is necessary to investigate the modification of the vibration characteristics of its design with the effect of nanomaterials and study the influence of other reinforced nanoparticle types on its features. Therefore, in this work, silicon nanoparticles were selected to investigate their effect on the vibration behavior of a shell structure. As a result, this work included studying the vibration behavior by testing the shell structure with a vibration test machine. In addition, after manufacturing the composite material shell with various silicon volume fractions, the mechanical properties were evaluated. In addition, the finite element technique with the Ansys program was used to assess and compare the vibration behavior of the shell structure using the numerical technique. The comparison of the results gave an acceptable percentage error not exceeding 10.93%. Finally, the results evaluated showed that the modification with silicon nanomaterials gave very good results since the nanomaterials improved about 65% of the shell's mechanical properties and vibration characteristics.

This paper comprehensively reviews research articles on linear and nonlinear performances of laminated shells. The study on composite surfaces gained popularity since the last decade. The composite shell problems for complex forms are difficult to solve analytically. Hence, the numerical solutions became popular. The invent of fast computers popularized the numerical approaches further among practicing engineers. Thin shell surfaces are widely popular to cover long unsupported spans in civil engineering; however, these are vulnerable to instability especially under transverse overloading. The stiffened surfaces addressed such problems. The detailed review on bare and stiffened surfaces highlights gaps in literature which can help the researchers to find out scopes of future research problems.
