WebThe compression set ( ASTM D395) of a material is the permanent deformation remaining after removal of a force that was applied to it. The term is normally applied to soft materials such as elastomers. Compression is normally measured in two ways: compression set A and compression set B. [1] Compression Set A [ edit] Webelasticity. Yield stress, marking the transition from elastic to plastic behaviour, is the minimum stress at which a solid will undergo permanent deformation or plastic flow …
