“…A final performance indicator that may be used to describe the behaviour of such systems is the weight effectiveness, which is given as c s g eff S e W *  [2] where g e is the crush efficiency and c s S is the specific energy absorption capacity. It is a useful indicator since the relative energy absorption capacity of the system is used in conjunction with an important variable, the stroke length.…”

Abstract.The present work presents both numerically and experimentally the quasi-static lateral compression of nested systems with vertical and inclined side constraints. The force-deflection response of mild steel short tubes compressed using two types of indenter's is examined. The variation in response due to these indenters and external constraints are illustrated and how these can contribute to an increase the energy absorbing capacity of such systems. The implicit version of the Finite Element code via ANSYS is used to simulate these nested systems and comparison of results is made with those obtained in experiments and were found to be in good agreement.Keywords: tubes, energy absorption, finite element, plastic deformation, lateral compression, quasi-static, ANSYS.

“…Research in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] focuses on the elaboration of working models of tubes, and provide comparison of the obtained results with analytical and experimental studies. The works consider the cases of static and dynamic axial and transverse straining of samples made from different materials, including the combined ones (sandwich-tubes).…”

Abstract. Dynamic impacts that became frequent lately cause large human and economic losses, and their prevention methods are not always effective and reasonable. The given research aims at studying the way of enhancing explosion safety of building structures by means of yielding supports. The paper presents results of numerical studies of strength and deformation property of yielding supports in the shape of annular tubes under static and short-term dynamic loading. The degree of influence of yielding supports was assessed taking into account three peculiar stages of deformation: elastic; elasto-plastic; and elasto-plastic with hardening. The methodology for numerical studies performance was described using finite element analysis with program software Ansys Mechanical v17.2. It was established that rigidity of yielding supports influences significantly their stress-strain state. The research determined that with the increase in deformable elements rigidity dependence between load and deformation of the support in elastic and plastic stages have linear character. Significant reduction of the dynamic response and increase in deformation time of yielding supports were observed due to increasing the plastic component. Therefore, it allows assuming on possibility of their application as supporting units in RC beams.

“…Therefore, the prediction of deforming behaviour is difficult. The compression process of metallic tubes of different shapes and sizes under different loading and different support conditions were investigated by many researchers in the past few decades by considering different analytical models of collapse [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] . Recently, finite element codes have also been employed to understand the compression process by few researchers [26][27][28] .…”

Quasi-static axial and lateral compression tests were conducted on aluminium tubes of circular, rectangular, and square cross sections on a universal testing machine (Instron model 1197). During the compression process, different tubes were collapsed in different modes of collapse. These compression processes were also modelled using FORGE2 finite element code. The code has the capabilities of automatic mesh generation, modelling of die, creation of material data file, carrying out the finite element computations, and post-processing of results. The deforming tube material was modelled as rigid-visco-plastic. Development of different modes of collapse was investigated experimentally and computationally. The experimental load-compression curves and deformed shapes are compared with the computed results and found in good agreement. It is found that the proposed finite element models of the different compression processes are capable of predicting the modes of collapse.
