Cracks Analysis in Zavin Concrete Dam Using Fracture Mechanics Approach
Most of the existing concrete dams are subjected to cracking. These cracks are caused by various factors such as construction practices, curing, loads and volume change of mass concrete which reduce the efficiency, failure or instability of concrete dams. Using fracture mechanics as a new method to estimate stability and durability of concrete dams is recommended in scientific publications in w...
متن کاملDamage 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 کاملStochastic nonlinear fracture mechanics finite element analysis of concrete structures
The paper summarizes the main outcomes achieved within the framework of the research project “Nonlinear fracture mechanics of concrete using stochastic finite elements and random fields”. The project focused on randomization of nonlinear finite element analysis of concrete structures. Theoretical as well as practical application aspects are presented emphasizing the conceptual framework and key...
متن کاملExperimental Analysis of Fracture and Damage Mechanics of Pre-Stressed Concrete Sleepers B70: Part B- Analysis
Initial cracks occur in high strength concrete sleepers for various reasons, such as shrinkage and wrong curing and long lifetime of over 50 years of sleepers. These cracks may lead to complete failure of the structure. In order to more accurately design the sleepers, fracture mechanics (not strength of materials) should be incorporated. In order to achieve this purpose, it is important to fore...
