“…Starbuck and Blake (1994) investigated the influence of some specific layers on composite cylinders and also conducted the verification tests. Some researchers (Hajmohammad et al , 2019; Messager et al , 2002; Lee et al , 2013) used a genetic algorithm to optimize the stacking sequence to maximize the unstiffened composite shell buckling, and it gives satisfactory results that agree well with the experimental results.…”

PurposeThe objective of this paper is to investigate numerically the buckling behavior of submersible composite cylinders.Design/methodology/approachBy means of FEM and golden section method, the search of hoop winding layers, longitudinal winding layers and helical winding layers are studied to optimize the buckling pressure. Considering the mid-strengthening cylinder, the size and distribution of stiffeners are studied systematically.FindingsThe results show that laying the hoop winding layers in the two outer sidewalls and the longitudinal winding layers in the middle of the shell is helpful to increase the buckling pressure, and the optimal helical winding angle changes with slenderness ratio.Originality/valueFor mid-strengthening cylinder, the effect of helical winding angle of stiffener on buckling pressure becomes weak gradually with the increase of stiffener thickness. With the increasing of the spacing between stiffeners, the buckling pressure increases first and decreases later. What is more, the mid-strengthening cylinder is less sensitive to the initial geometric imperfections than unstiffened shells.

“…The results of using these functions to optimize the arrangement in the composite cylinder have shown decreasing of mass up to 28%. [35][36][37] Furthermore, the employed mapped fitness functions thoroughly analyzed the parameters of "mass" and "buckling load" simultaneously, allowing us the opportunity of achieving considerably highquality results. The desired fitness functions are presented as (35) in which M and P cr represent the weight and buckling load, respectively.…”

In this research, the lateral buckling analysis and layup optimization of the laminated composite of web and flanges tapered thin-walled I-beams based on maximizing lateral-torsional stability strength and minimizing mass/cost of the structure are investigated. The classical lamination theory and Vlasov’s model for thin-walled cross-section are adopted to establish the total potential energy for thin-walled symmetric balanced laminated beams with varying I-section. By implementing the Ritz method, an explicit formulation for the lateral-torsional buckling load of a double-tapered beam subjected to transverse loading is then derived in terms of the load height parameter and stiffness quantities. Subsequently, the optimal arrangements of layer sequences are obtained using the non-dominated sorting genetic algorithm (NSGA-II) and properly defined objective function. The critical factors of fitness function as lateral buckling strength and the mass of the structure with critical limitations as ply angle, number of layers for the web and flanges, and the thickness of all section walls are considered in this study. Finally, the optimal layer arrangement for the web and flanges are separately determined and discussed. The results show that the presented optimization procedure and layups patterns lead to increasing the lateral-torsional buckling capacity about 52% compared to the conventional angle-ply and unidirectional layups for the web and flanges, respectively.

“…Composite usage has been rising in different industrial zones, including aerospace, medical engineering, and civil engineering, in recent decades. [246,247] Because of having multiple materials with various properties, residual stress examination is complex and needs to be investigated more deeply in these materials. Pramanik et al [248] conducted a deep examination on the effects of ceramic-reinforced particles on the residual stress in turning aluminum alloy.…”

The accurate determination of residual stresses has a crucial role in understanding the complex interactions between microstructure, mechanical state, mode(s) of failure, and structural integrity. Moreover, the residual stress management concept contributes to industrial applications, aiming to improve the product's service performance and life cycle. In this regard, the industry requests rapid, efficient, and modern methods to identify and control the residual stress state. This review article contains three main sections. The first section covers different residual stress determination methods and reports the advancements over the recent decade. The second section includes the role of residual stresses in the performance of a broad range of materials including metallic alloys, polymers, ceramics, composites, and biomaterials. This is presented by classifying different science areas dealing with residual stresses into two main groups, including “origins” and “effects” of residual stresses. The range of topics covered are “welding, machining, curing/cooling, and spray coating processes,” “medical and dental sciences,” and “fatigue and fracture mechanisms.” The third section summarizes various strategies to effectively control residual stresses through different manufacturing procedures. It is hoped that the data provided herein serves as a valuable up‐to‐date reference for engineers and scientists in the field of residual stress.
