Creep is a rate dependent material nonlinearity in which the material continues to deform under a constant load (ANSYS). Creep is highly time dependent and it displays its effects over a long time. Creep has 3 stages:. 1)A coil of solder will be suspended from a clamp into a glass.. Boiling water will then be added.. You must visually inspect the coil every 30 seconds for 10 minutes and note any changes.. 2)An aluminium rod will be handed to each pair.. Dara . Navaei. , Siegfried Malang, . Xueren. Wang. ARIES .

The difference in the thermal expansion between the materials introduces thermal stresses in the structure. The solder, connecting the resistor to the printed circuit board, is seen as the weakest link in the assembly.
