    Abstract

    For crack prediction in permanent mold casting of lead-free bronze, elasto-viscoplastic and elasto-plastic thermal stress analyses were performed and compared with the casting tests. The elastoviscoplastic model was constructed by the method which enables to determine rheological properties without steady state stress in experiments. Maximum deviatoric principal (only by the elastoviscoplastic analysis) and hydrostatic stress were in reasonable agreement with the locations of cold cracking and hot tearing in the casting tests, respectively. It was suggested that considering the rheological properties of semi-solid alloys was important especially to predict cracks during and after solidification
