Temperature Dependent Elastic Constants of Directionally Solidified Superalloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Directionally solidified superalloys have been extensively used as turbine blade materials to improve creep-rupture and thermal fatigue performances. Turbine blades are subjected to fluctuant ...
Effective Temperature Differential in Concrete Pavements
Publisher: American Society of Civil Engineers
Abstract: To evaluate curling stresses in concrete pavements requires the input of a temperature differential or even a temperature distribution between the top and bottom of slabs. However, the slab temperature fluctuates throughout ...
Two Approaches of Finite-Element Modeling of Ballasted Railway Track
Publisher: American Society of Civil Engineers
Abstract: Use of a ballast is still popular in railway engineering due to its resilience, relatively low noise, and convenience in construction and maintenance. The ballast layer was modeled with two modeling approaches in this ...
Three-Dimensional Pavement Analysis with Nonlinear Subgrade Materials
Publisher: American Society of Civil Engineers
Abstract: The nonlinear models of pavement base and subgrade were briefly reviewed. Subroutines of the three-dimensional finite-element analysis in the ABAQUS package were developed for nonlinear behavior of a coarse-grained base ...
