โœฆ Synopsis

Finite element algorithms are presented for the entire casting process from the mould รฟlling stage to the prediction of the รฟnal distorted shape. The various algorithms available in the literature for solidiรฟcation modelling are discussed in detail. Special emphasis is given to the coupling of the solidiรฟcation analysis based on the heat conduction equation with uid ow or thermal stress analysis. Finally, some results are presented to demonstrate the capabilities of the numerical models.

Vacuum arc remelting is a process for producing homogeneous ingots of reactive and macrosegregation-sensitive alloys. A mathematical model of the transport phenomena in the ingot melt is presented together with a discussion of the various simplifying assumptions and approximations that make the prob

The protonation of an aqueous solution of two ampholytes AH and BH next to a gel buffered by immobilized acid moieties IH has been studied by finite element simulation in an iterative scheme. A ten species model has been formulated, taking into account transient diffusion and equilibrium kinetics of

When a metal matrix composite (MMC) is cooled down from the fabrication or annealing temperature to room temperature, residual stresses are induced in the composite due to the mismatch of the thermal expansion coe cients of the matrix and reinforcement. A thermomechanical model describing these proc

In this work we present a รฟnite element formulation to simulate the รฟlling of thin moulds. The model has as starting point a 3-D approach using either div-stable elements, such as the Q2=P1 element (tri-quadratic velocities and piecewise linear, discontinuous pressures) or stabilized รฟnite element f
