Damage Assessment using an Inverse Fracture Mechanics approach
This paper studies the application of an inverse methodology for problem solving in fracture mechanics using the finite element analysis. The method was applied to both detection of subsurface cracks and the study of propagating cracks. The procedure for detection of subsurface cracks uses a first order optimization analysis coupled with a penalty function to solve for the unknown geometric par...
متن کاملFracture toughness measurements on igneous rocks using a high-pressure, high-temperature rock fracture mechanics cell
A sound knowledge of mechanical properties of rocks at high temperatures and pressures is essential for modelling volcanological problems such as fracture of lava flows and dike emplacement. In particular, fracture toughness is a scale invariant material property of a rock that describes its resistance to tensile failure. A new fracture mechanics apparatus has been constructed enabling fracture...

متن کاملFracture mechanics
In this article, after a brief description of some signi®cant catastrophic structural failures going back to the period when iron and steel began to replace wood and masonry as the primary structural materials, the historical development of the ®eld of fracture mechanics is discussed. First, the basic concepts of the ®eld, the motivation underlying their development and the key contributions ma...
متن کاملProbabilistic Fracture Mechanics for Nonlinear Structures
A probabilistic methodology has been developed for fracture-mechanics analysis of nonlinear cracked structures. The methodology involves nonlinear ®nite element analysis using well-known commercial codes; statistical models for uncertainty in material constitutive law, fracture toughness, and loads; and standard reliability methods for evaluating probabilistic characteristics of elastic±plastic...
