Project Details

Title:A Modified Approach for Predicting Fracture of Steel Components under Combined Large Inelastic Axial and Shear Strain Cycles
Principal Investigators:Hussam Mahmoud
University:Colorado State University
Grant #:DTRT13-G-UTC38 (MAP21)
Project #:MPC-446
Keywords:axial loads, bridge members, fatigue (mechanics), fracture properties, inelastic stress, service life, shear strain, steel bridges


The objectives of this project are as follows: 1) Collect experimental data on identifying mathematical models for predicting low-cycle fatigue (LCF) and ultra-low cycle (ULC) fatigue behavior in metallic structures; 2) Generate data from experimental testing to be used for predicting LCF and ULCF response of bridge girders; and 3) Develop a framework for fracture predictions.
