Rigid-perfectly plastic
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. WebWhen we refer to flexible plastic, we actually mean PVC (polyvinyl choride), which is rendered more flexible through the addition of plasticisers. Flexible profiles are supplied in packs of 3 x 25 metre COILS. On the other hand, …
