Hassan Diab,Marc Frappiercontrast to traditional failure criteria (maximum stress/strain, Tresca, von Mises, Coulomb–Mohr, etc.) which ignore the presence of defects. Since structures and machine components cannot be constructed without defects, on the grounds of practicality, fracture mechanics is used to determine either

Philippe Facon,Régine Laleau,Hong Phuong Nguyender. In geometries of this kind the statement of theorems, after fixing the coordinate system, involves only some equality relations. We have proposed a mechanical method which usually is quite efficient and can be used to prove rather difficult theorems. Practice will show the extent of efficiency

Such a fundamental alteration in cardiopulmonary mechanics frequently leads to complications and therapeutic compromise (Montgomery et al. 1985). High airway and intrath

Z: A Formal Specification Notationd by a library of operators known as the ‘Z toolkit’, which is largely formally defined within the Z notation itself . The operators have a large number of algebraic laws which aid in the reasoning about Z specification. As well as the mathematical notation, there is a ‘.’ notation to aid in the
