What is the Difference between permissible and allowable stress?
Permissible stress design (in USA construction more commonly called allowable stress design) is a design philosophy used by civil engineers. The designer ensures that the stresses developed in a structure due to service loads do not exceed the elastic limit.
What is the difference between Allowable Stress Design and Working Stress Design?
allowable stress design-2/3rd of yield working stress design is process yield

Are vehicles designed with both plastic and elastic values to absorb energy forces in a manner that will reduce the direct forces that reach the vehicle occupant?
Yes, vehicles are designed with both plastic and elastic components to absorb and dissipate energy forces during a collision. Plastic components deform permanently to absorb energy, while elastic components deform temporarily and then return to their original shape, helping to reduce the direct forces that reach the vehicle occupants. This design approach helps to improve occupant safety during a crash.

Difference between elastic and plastic deformation?
Elastic deformation returns to it's original shape after a strain is applied. Plastic deformation returns to a deformed shape after a strain is applied. The material's molecular bonds are strained to the point of fracture, making it not possible to return to the same state. Elastic deformation will return to its original shape. Plastic deformation is when you alter the original form. To understand more on this subject you might investigate failure analysis literature. Lots of good stuff there ratchet marks, beach marks, reverse bending etc... I believe the U.S. metallurgical society has the best reference material on this subject. A temporary shape change that is self-reversing after the force is removed, so that the object returns to its original shape, is called elastic deformation. In other words, elastic deformation is a change in shape of a material at low stress that is recoverable after the stress is removed. Examples would be the loading of a bridge or building support beam where the loads remain within the original design parameters, or the use of a safety pin where when it is opened it returns to it's unloaded shape. When the stress is sufficient to permanently deform the metal, it is called plastic deformation. Examples would be the building support beams for the twin towers, where the heat generated by the fires decreased the strength of the steel and allowed it to deform plastically, or the loads that are applied to a section of electrical conduit or mechanical piping in order to bend them into a specific shape. in elastic def. , the material returns to its original shape once force is removed. in plastic, the deformation is permanent and the material doesn't return to its original shape the elastic deformation happens in yield point and elastic deformation back to original size but plastic deformation will not back tto original size.
