繰返し荷重を受ける切欠材の弾塑性挙動

For an accurate residual life assessment in structural components subjected to cyclic loading, detailed elastoplastic structural analysis is important for areas with strain concentration. The present paper shows some experimental and computational results of elastoplastic behavior for notched plates with different strain concentration factors subjected to two types of zero-to-tension cyclic loadings. Numerical calculation is performed based on the endochronic model for cyclic plasticity, showing good agreements with experimental results.
