U形切槽均匀拉伸板应力集中系数分析

摘要

应用ANSYS有限元软件,分析了线弹性材料单边U形切槽均匀拉伸板的应力集中系数,得到了U形切槽均匀拉伸有限平板的应力集中系数随切槽深度和宽度变化的规律,并将计算结果与已有文献进行了对比,验证了数值计算结果的准确性和可靠性,同时拓展了现有文献数据的范围.%The paper adopts the ANSYS finite element software,analyzes the stress concentration coefficient of the single-sided U-shaped grooving uniform tensile plates with linear viscoelatic materials,concludes the coefficient of the U-shaped grooving uniform tensile plates with finite plane plates,compares the calculation result and existing literature,proves the accuracy and reliability of the numeric calculation results,and extends the scopes of existing literature.
