“…Note that the next adjacent sub-matrix is obtained with an increase of i, while an increase of j will represent a stride of 5 Â m for Shadmehri's model or 10 Â m for the other models. The expression for q has a close relationship with the bandwidth of the final stiffness matrices, and the adopted formula, taken from the work of Shadmehri [5], leads to a short bandwidth making it very efficient to use with sparse matrix solvers during the solution steps.…”

“…The verification of the proposed models for conical structures was performed using pure axial compression results from the recently published model of Shadmehri et al [5], for boundary conditions of type 3. Finite element results were used to verify the accuracy of all the modes and to verify the proposed models for the type 1 of boundary conditions.…”

“…This assumption is required in order to allow the derivation of analytical solutions for the linear buckling problem. Shadmehri et al presented in recent studies [5,6] a semianalytical approach based on the Ritz method for the calculation of the linear buckling load of laminated composite cones under axial compression using the SS3-type of simply supported boundary conditions (cf. The formulation presented in this study is based on the Ritz method and the investigation of different approximation functions is facilitated by the use of a matrix notation.…”

“…The crush failure load and first peak load in the composite testing increases remarkably with the increase in the number of layers, content of fibres, composite thickness and bending stiffness. Shadmehri et al [46] proposed a semi-analytical approach to get the linear buckling response of conical composite shells under axial compression load. The results showed that the critical buckling load decreases with increase in the semi-apical angle and it is more prominent as the semi-cone angle exceeds .…”

Abstract. Collapsible impact energy absorbers play an important role of protecting automotive components from damage during collision. Collision of the two objects results into the damage to one or both of them. Damage may be in the form of crack, fracture and scratch. Designers must know about how the material and object behave under impact event. Owing to above reasons different types of collapsible impact energy absorbers are developed. In the past different studies were undertaken to improve such collapsible impact energy absorbers .This article highlights such studies on common shapes of collapsible impact energy absorber and their impact behaviour under the axial compression. The literature based on studies and analyses of effects of different geometrical parameters on the crushing behaviour of impact energy absorbers is presented in detail. The energy absorber can be of different shape such as circular tube, square tube, and frustums of cone and pyramids. The crushing behaviour of energy absorbers includes studies on crushing mechanics, modes of deformation, energy absorbing capacity, effect on peak and mean crushing load. In this work efforts are made to cover major outcomes from past studies on such behavioural parameters. Even though the major literature reviewed is related to metallic energy absorbers, emphasis is also laid on covering literature on use of composite tube, fiber metal lamination (FML) member, honeycomb plate and functionally graded thickness (FGT) tube as a collapsible impact energy absorber.

This paper presents the state of art in the field of composite shells with focus on stress analysis, buckling and post-buckling responses under mechanical and thermal loading. Many researchers have investigated the buckling and post-buckling responses of cylindrical, conical, spherical, thin and thick composite shells with single and doubly curved shells under mechanical and thermal loading. From the literature it can be inferred that hydrostatic pressure, axial compression and thermal environment influence the buckling behavior of laminated composite shell significantly. An effort is taken to review the research on buckling and postbuckling responses of cylindrical and conical shaped shells under mechanical and thermal loading and their behavior during buckling and post-buckling conditions.
