creep deformation

Creep deformation refers to the slow, permanent change in the shape or size of a material when it is subjected to a steady, long-term stress or load, usually at high temperatures. Over time, the material's internal structure gradually rearranges, causing it to stretch or deform even if the applied force remains constant. This process is common in materials like metals and plastics used in high-temperature environments, such as turbines or engines. Understanding creep is important for predicting how long materials can safely withstand certain conditions without failing.
