| Abstract: | The calculation method is studied for calculation the reliability of mechanical Stress/Strength Interference.When the strength obeys Weibull distribution and the stress obeys Gauss distribution,the integration interval of calculation reliability is subdivided to some subdomain.In the subdomain of the integration the numerical integration formula of Gauss Lagendre is applied.The adaptive algorithm is presented in this paper at the request of the calculation reliability accuracy,which can autonomously adjudge the calculation number of time. |
