【摘要】 提出了一种P-S-N曲线快速测定方法———虚拟子样法,并运用连杆、焊接试样疲劳试验及材料数据进行了验证。结果表明,与成组法相比,虚拟子样法的平均误差一般在5%以内,最大误差一般不大于10%。更多还原

【Abstract】 This paper presents a rapid measuring method of P -S -N curve-- - virtual sub specimen method.The verifications are conducted by fatigue evaluation tests of connecting rod,weld specimens and material data.The results have shown that comparing with group method,the error in average of this virtual subspecimen method is within5%,max error is under10%.更多还原
