摘要: A new theoretical model of plastic behavior circular metal tubes during the contraction process as a forming and energy absorber processes is presented in this study. Some relations are developed to predict axial load versus displacement process, based on model. quasi-static experiments were performed aluminum brazen validate analysis. In research, effects tube radius, ratio, wall thickness angle conical die absorption characteristics under loading investigated by experimental methods. Results show that there an admissible agreement between results measurements. Experimental steady force end zone which important factor viewpoint absorption. Also, increases in...
