For this purpose, an infinite piezoelectric plate cut along to equal semipermeable collinear cracks is considered. Stroh’s formalism and complex variable technique are used to formulate the problem. The closed-form analytical expressions are derived for the various fracture parameters viz. crack opening displacement, crack opening potential drop, intensity factors, and energy release rate. Moreover, the quadratic equation is derived to find the electric displacement inside the crack gap media. For a poled PZT-5H ceramic plate, an illustrative numerical investigation is implemented to demonstrate the effect of arbitrary polarization on the various fracture parameters.","PeriodicalId":41486,"journal":{"name":"Strength Fracture and Complexity","volume":"10 1","pages":"129-144"},"PeriodicalIF":0.7,"publicationDate":"2018-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/SFC-170205","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46606105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a nonlinear least squares fit algorithm and the physical assumption that the one-sided Lower Tolerance Limit (<i>LTL</i>), at 95% confidence level, of the fatigue life, i.e., the minimum cycles-to-failure, <i>minNf</i>, of a full-scale component, <i>cannot be negative</i> as the lack or \"Failure\" of coverage (<i>Fp</i>), defined as 1 - <i>p</i>, approaches zero, we develop a new fatigue life model, where the minimum cycles-to-failure, <i>minNf</i>, at extremely low \"Failure\" of coverage, <i>Fp</i>, can be estimated. Since the concept of coverage is closely related to that of an inspection strategy, and if one assumes that the predominent cause of failure of a full-size component is due to the \"Failure\" of inspection or coverage, it is reasonable to equate the quantity, <i>Fp</i>, to a Failure Probability, <i>FP</i>, thereby leading to a new approach of estimating the frequency of in-service inspection of a full-size component. To illustrate this approach, we include a numerical example using the published data of the fatigue of an AISI 4340 steel (N.E. Dowling, <i>Journal of Testing and Evaluation</i>, ASTM, Vol. 1(4) (1973), 271-287) and a linear least squares fit to generate the necessary uncertainties for performing a dynamic risk analysis, where a graphical plot of an estimate of risk with uncertainty vs. a predicted most likely date of a high consequence failure event becomes available. In addition, a nonlinear least squares logistic function fit of the fatigue data yields a prediction of the statistical distribution of both the ultimate strength and the endurance limit.</p>","PeriodicalId":41486,"journal":{"name":"Strength Fracture and Complexity","volume":"11 ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/SFC-180223","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38703902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
