An inverse solidification of pure substance problem in two dimensions
This paper is concerned with an inverse problem involving a two-phase moving boundary in two dimensional solidification of pure substance. Using a unique continuation result due to Saut and Schcurer we prove a uniqueness result. © 2005 Elsevier Ltd. All rights reserved.
متن کاملThe Adjoint Method for an Inverse Design Problem in the Directional Solidification of Binary Alloys
This paper presents a systematic procedure based on the adjoint method for solving a class of inverse directional alloy solidification design problems in which a desired growth velocity v f is achieved under stable growth conditions. To the best of our knowledge, this is the first time that a continuum adjoint formulation is proposed for the solution of an inverse problem with simultaneous heat...
متن کاملAn Adjoint Method for the Inverse Design of Solidification Processes with Natural Convection
This paper presents a nite element algorithm based on the adjoint method for the design of a certain class of solidi cation processes. In particular, the paper addresses the design of directional solidi cation processes for pure materials such that a desired freezing front heat ux and growth velocity are achieved. This is the rst time that an in nite-dimensional continuum adjoint formulation is...
متن کاملHOT CRACK FORMATION IN PURE CU AND CU-30%ZN ALLOY DURING IN SITU SOLIDIFICATION
The hot cracking susceptibility can be determined by establishing the transition temperature between brittle and ductile fracture at high temperature tensile testing of in situ solidified samples. High temperature tensile properties were determined for commercial cathodic pure Cu and Cu- 30%Zn alloy. The transition temperatures for pure Cu and Cu-30%Zn were evaluated from ultimate tensile stres...
