Page: Theories of failure
... - Practically the mechanical components are subjected to several types of loads simultaneously. When the component is subjected to several types of loads, combined stresses are induced. - The design of machine parts subjected to these loads should be related to experimentally determined properties ...

Page: Manufacturing considerations of forging
... Forging is a deformation process in which a solid metal is forced under pressure to undergo extensive plastic deformation into finished or near-to-finished shape. The forging produces a fiber structure. The fiber lines of the forged parts can be arranged in required direction. Hence it improves the ...
