The explicit finite element method ( fem ) based on the varying time - step was selected to analyse the dynamic roll - pass process ; the nodes on the leading face of the steady - state elements set was extracted and projected onto a plane to give the required mesh, also called the origin mesh ; the implicit fem was selected to analyses the inter - pass transient thermal process ; a geometric part from the mesh was generated and meshed by using the quadrilateral elements, a heat transfer analysis was selected to transfer the node temperature data ; a new model was created by using hexahedral elements, mapping the node temperature and the equivalent plastic strain on the integration points
利用基於變步長中心差分格式的顯式積分方法分析瞬態軋制過程；提取穩態單元集節點形成截面網格；利用隱式積分方法分析軋制道次間隙瞬態溫度場；對型鋼斷面進行平面四邊形網格劃分並映射節點溫度數據；利用六面體單元構建有限元分析模型，映射單元節點的溫度、積分點的等效塑性應變，進行數值分析。 -
