| Summary: | The purpose of this paper is to study the collapsibility of internal structure for
Acrylonitrile butadiene styrene (ABS) P400 materials as a sacrificial patterns in investment
casting(IC) . Two different internal patterns structure which consist hollow and square 90° were
performed by Insight software . Experiment were perform by applying 3D coupled thermal
mechanical finite element analysis on cube ceramic shell during burnout stage. As numerical
observation the deformation stress for cube square 90° and hollow models have been evaluated by
increasing the temperature during heating up to 700℃. It is found that both pattern start to buckling
over the autoclave temperature throgh simulation observations and shows no cracking defect occured
at ceramic mould. |
