## A B S T R A C T In the discussion of the form taken by the expression for the energy for a crack of finite width, an energy term analogous to the plastic work of fracture was introduced. This term is shown to account for the normally observed relation between failure stress and crack length for

Al~traet--Fracture Mechanics of Ductile Metals (FMDM) theory is used to obtain the plane strain fracture toughness, K~, for different materials. The traditional approach for obtaining the K~ value is to conduct several standard tests on cracked plates that are costly and time consuming. The fracture
Fracture surface energy, obtained by the work of fracture method using notched beams, provides a simple and direct measure of the "toughness" of hardened cement paste that avoids relying on complex analytical procedures which may not be readily applicable to this type of material. Nevertheless, it i
The liine-teniperature dependence of the cohesive fraclure energy is deduced from experiments on a centrally cracked sheet of butadiene-acrylonitrile-acrylic acid viscoelastic terpolymer crosslinked with an epoxy curing agent. Analytic results based upon a cylindrical flaw model of the crack permit
## Abstract Semiβempirical energy calculations for an internal ProβPro dimer are presented that take into account the nature of the flexibility of the proline ring due to its puckering. Calculations show that three stable conformations are available for the dimer: the __cis__ (Ο = 0Β°, Ο = 160Β°); th
