Numerical and Analytical Investigation of a Cylinder Made of Functional Graded Materials under Thermo-Mechanical Fields
This research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. Heat conduction equation in cylindrical coordinate system is solved. Thermal conductivity coefficient is graded along the radial direction. By considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can b...

متن کاملA Review of Early-Age Properties of Cement-Based Materials
Immediately after placement, gravitational forces and the local drying environment begin to influence the (micro)structure of a cement paste, mortar, or concrete. Depending on the mixture’s water-to-cementitious materials mass ratio (w/cm) (and aggregate volume fraction), the initial freshly cast material may be thought of either as a concentrated suspension of rigid particles in water or as a ...
متن کاملEarly-Age Properties of Cement-Based Materials: II. Influence of Water-to-Cement Ratio
The influence of water-to-cement mass ratio (w/c) on early-age properties of cementbased materials is investigated using a variety of experimental techniques. Properties that are critical to the early-age performance of these materials are tested, including heat release, semiadiabatic temperature, setting time, autogenous deformation, and strength development. Measurements of these properties u...
