β¦ Synopsis
A material expert system has been established for the evaluation of critical flaw size in structural components subjected to fatigue loads. Specimen/size, load amplitude and mean stress and material type can be varied such that their combined effects can be accounted for in determining the condition of global instability. This corresponds to the onset of rapid crack propagation. This computer expert system permits quick access to material selection and geometry alteration design. (D. S. Prerau, Developing and Managing Expert System. Addison-Wesley, New York (1990)).

ANEMIA is a knowledge-based consultation program for anemic states. It has been built using an artificial intelligence programming scheme, called EXPERT, which was developed at Rutgers University. At present, ANEMIA is able to provide assistance in the diagnosis and management of 64 disease entities
Attstract-The consistency of four strength theories with fracture mechanics is studied by using 6nite element methods. This is carried out by calculating the fracture toughness of a material, as the critical value of the stress intensity factor of a centre-cracked infinite sheet, and checking whethe
