Abstract: A simple method is proposed for determination of fracture energy of materials exhibiting quasi-brittle behavior during mode I cracking. A series of graphs showing the relationship between the nondimensional peak load and ...

Abstract: The paper deals with a cohesive crack model in which the cohesive (crack-bridging) stress is a specified decreasing function of the crack-opening displacement. Under the assumption that no part ...

Abstract: The preceding paper is extended to the analysis of size effect on strength and ductility of structures. For the case of geometrically similar structures of different sizes, the criterion of ...

Abstract: A simple analytical model has been developed for prediction of size‐dependent maximum loads of concrete‐beam specimens subjected to mode‐I rupture. The analytical model is cast within a framework of a fictitious crack ...

Abstract: A boundary element program based on a fictitious crack‐model (FCM) was used to study the size effect in concrete during mode‐I nonlinear fracturing. Series of numerical parametric studies were performed to examine the ...

Abstract: Vertical penetration of an object through a floating elastic‐brittle plate from the bottom up or the top down is studied. Based on field observations, it is assumed that many symmetric cracks grow radially from a small ...

Abstract: The problem of static penetration of an object through a sea ice plate is studied as a two‐dimensional fracture problem using linear elastic fracture mechanics. The ice sheet floating on water is modeled as a thin elastic ...

Abstract: A simple analytical model is developed to predict the average crack spacing and crack depth in highway pavements due to thermal loading. The pavement is modeled as a beam on a Winkler elastic foundation. The effect of ...
