Title : ( Deterministic and Stochastic Coupled Thermoelasticity Analysis in Thick Hollow Cylinder Subjected to )
سیدمحمود حسینی,چکیده
Safe and reliable design for cylindrical structures and shells under thermomechanical shock loadings or structures subjected to transient boundary conditions requires the engineering parameters to be considered as uncertain and random variables obeying physical conditions during manufacturing processes of materials. Some of the most important parameters, which are considered as input parameters in some engineering problems, are mechanical properties such as modulus of elasticity, density, and heat transfer coefficients. The uncertain mechanical properties can be randomly generated using the Monte Carlo simulation with various coefficients of variations (COVs) and normal distribution. The deterministic and stochastic analysis of coupled thermoelasticity problems as well as thermoelastic wave propagation in cylindrical structures is helpful for prediction of all possible responses caused by uncertainties of mechanical properties.
