Prediction of Meniscus Shape in Two-section Slitless Mold for Soft-contact Electromagnetic Continuous Casting;

Heat transfer in two-stage slitless mold for soft-contact electromagnetic continuous casting and thickness of initial solidified shell were analyzed through numerical simulation method.

The development and problems of soft-contact electromagnetic continuous casting technology were briefly introduced.

Magnetic field distribution and molten metal meniscus behavior in soft contact electromagnetic continuous casting mold;

Two contact models,the classical Coulomb contact model and the modified Coulomb contact model,are used in a fully coupled thermo-mechanical numerical model of friction stir welding, and the suitabilities of the two models to simulate the welding process are analyzed.

Based on the first-order shear deformation theory of the composite laminated plate,an FEA model and the method of free vibration analysis for the composite laminates with multiple through-width delaminations were developed,and a linearity contact model was established to simulate the interaction between upper and lower sub-laminates along the delaminated region during the vibration process.

Fractal surface was introduced into the average flow model and effect of elastic-plastic contact deformation of fractal surfaces on the flow factors and contact factor were analyzed based on the M-B fractal contact model for partial film lubrication.
