WebNov 3, 2024 · Summary This chapter discusses typical feature of impulsively loaded rigid-plastic structures, the dynamic response that can be clearly divided into two phases: a transient phase characterized by the presence of traveling plastic hinge (s), and a subsequent modal phase, in which the hinge positions remain stationary. WebThe concept of perfect plasticity is associated with the mechanical behaviour of materials that while yielding do not present a further increase of stress for an increase in strain (i.e. a plateau is observed in two dimensions, cf. Fig. 4.19 ). albion 2 vst
