Part A- Experimental: Experimental Analysis of Crack Propagation in Pre-stressed Concrete Sleepers by Fracture Mechanics
This study investigates propagation of mode I crack in B70 pre-stressed concrete sleepers by fracture mechanics approach. A new experimental analysis is done for notched B70 pre-stressed concrete sleepers with Replica test and image analysis. A scanning electron microscope test (SEM) and an image analysis are applied for the Replica test in order to determine crack length and crack mouth openin...
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...
متن کاملCracks 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 کاملTitle Meshfree Sequentially Linear Analysis of Concrete
3 New meshfree method employing the Node-based Smoothed Point Interpolation Method 4 (NS-PIM) is presented as an alternative to the non-linear finite element approach for concrete 5 members. The non-linear analysis is replaced by sequentially linear analyses (SLA), and 6 smeared, fixed concrete cracking model was used. A notched concrete beam was employed 7 for validation. Using a crack band wi...
