在这项研究中,提出了一种逆分析方法,用于确定从测量位移的幂律硬化材料的材料特性。利用数字图像相关法测量了载荷作用下试件表面的位移分布。采用虚场法和总应变理论相结合的方法进行反分析。通过对铝合金三点弯曲试件的分析,验证了该方法的有效性。结果表明,该方法可以从位移场中识别材料屈服后的性质。
In this study, an inverse analysis method for determining the material properties from measured displacements for a power-law hardening material is proposed. Displacement distributions on a specimen surface under load are measured using digital image correlation. The virtual fields method combined with the total strain theory is used as a method for inverse analysis. The effectiveness of the proposed method is demonstrated by applying to aluminum specimens under three-point bending. Results show that the material properties after yielding can be identified from the displacement fields by the proposed method.
