WebFrom what I understand, creep manifests as a slow increase in strain under the presence of stress, but I couldn't find many academic papers which describe the long term creep behavior of these polymers (especially considering there are many different grades of these materials). Vote. 0 comments. Best. Add a Comment. WebCreep is defined as slow plastic deformation at stress levels below the normal yield stress. Creep is very slow at room temperature for most materials. The difference between ceramics and metals is the temperature at which creep occurs. Creep occurs when the temperature is above about 0.4-0.5 Tm. Metals will therefore creep at relatively low ...
