A thermo-kinetic model for the transient thermal stress field of the wall-shaped part produced using laser direct powder deposition process is developed. In case of numerical modeling, the capabilities of ANSYS parametric design language and the the ‘birth and death’ element technique were employed. The distribution of the thermal stress of the wall-shaped part at different time was calculated by the model. Results show that during process, the X-direction thermal stress within top layer of the wall-shape part and that within the interior deposited layers of the wall-shape part was tensile stress and compressive stress, respectively. The deformation of the wall-shaped part and base plate was also calculated.

Cluster Design

For the purpose of studying material cluster design and shape design of a certain arc-shaped thermal-protection component rationally, the ablation behavior and thermal stress distribution are studied by using the method of finite element numerical simulation. The study includes ablation tests, numerical simulation of temperature field, calculation of ablation thickness and numerical simulation of unsteady thermal stress field of the component. The simulation results are consistent with the results of ablation tests, which shows that the shape design of the arc-shaped thermal-protection component is rational and the dangerous periods of the component ablation are the time of initial heating and initial ablation boundary retreat.

We deal with a transient thermal stress problem in an infinitely long circular cylinder due to a nonuniform heat supply in circumferential and longitudinal directions on its cylindrical surface. The analysis is developed using the Boussinesq-Papkovich functions. Numerical results are given for several forms of heat supply.
