To provide a deformation analysis method for a material to be pressed capable of performing a deformation analysis at the time of press forming in short time.SOLUTION: A deformation analysis method for a material to be pressed as the method for analyzing deformation of the material to be pressed when performing mold-opening from a state of performing mold-clamping of the material to be pressed with a press mold includes a correlation acquisition step S41 of acquiring correlation between a stress distribution generated on the material to be pressed when applying a heat load to the material to be pressed and the heat load, a heat load applying step S42 of substituting the stress distribution generated on the material to be pressed in a mold-clamping state with the heat load based on correlation to apply the heat load to an analytic model 10 of the material to be pressed and a deformation analysis step S43 of analyzing the deformation of the analysis model 10 of the material to be pressed when turning to the mold-opening state from the mold-clamping state.SELECTED DRAWING: Figure 2 【課題】プレス成形時の変形解析を短時間で実施可能とする。【解決手段】本発明に係る被プレス材の変形解析方法は、被プレス材をプレス型で型締めした状態から型開きしたときの被プレス材の変形を解析する方法であって、被プレス材に熱荷重を付与した際に被プレス材に生じる応力分布と、熱荷重との相関を取得する相関取得ステップＳ４１と、相関に基づいて、型締め状態で被プレス材に生じる応力分布を熱荷重で代替して被プレス材の解析モデル１０に付与する熱荷重付与ステップＳ４２と、型締め状態から型開き状態としたときの被プレス材の解析モデル１０の変形を解析する変形解析ステップＳ４３とを備える。【選択図】図２
