The crankcase takes on a local complex load that must be born reliably for several hundred thousand kilometers and many years. This results from the complex of loads that act on the component and that are composed of gas forces in the combustion cycle, of reaction forces in the power cycle and of bends and screw joints. There are also the interior forces from the thermal expansion, internal stresses, the weight force of the component's own mass, the weight force of screwed on components, such as the crankshaft and the cylinder head, and the forces from the thermal expansion of the add-on parts that are transmitted via the screw connection.
The highest thermal stress is usually found in the web area of the cover plate
