In addition, bilinear stress-strain and crack opening relations are presented. In this paper these relations are verified on the basis of theoretical considerations and available experimental data.

Book 1991 review was presented by Drs W.G. Knauss and AJ. Rosakis as Guest Editors in four issues, January-April 1990, under the general title of Non­ Linear Fracture. It contained sections on damage mechanisms, interfaces and creep, time depen­ dence, and continuum plasticity insofar as they affect the mech

Tensile fracture of concrete at high loading rates taking account of inertia and crack velocity effecrack at high loading rates. It turns out that the quite crude model predicts rather accurately the relation between apparent strength and loading rate, the influence of concrete quality on this relation, and the relation between crack propagation velocity and loading rate.
