Abstract
"This study seeks to explore the effects the geometry of prestressing tendons on the crack formation of prestressed concrete crossties. Multiple tendons’ indentation patterns are explored with variable dimensions such as the shape and volume of the indentation, the depth of the cut into the steel, and the sidewall angle. The preliminary exploration is carried out using ABAQUS finite element analysis software on local processors in conjunction with the stampede2 high performance computer in order to develop the advanced numerical framework based on a parallel computing algorithm. In addition, the concrete damaged plasticity model that includes a degraded modulus of elasticity and the compounding compressive and tensile damage factors to concrete, is used for continued research into the impact of these factors. The visualization of these effects are provided using the local results generated by ABAQUS as well as the visualization toolkit ParaView after the analysis on the high performance computer."
