“…Crack length determinations were made using standard elastic compliance and optical methods. The compliance coefficients for the DC(T) specimen were determined in this study and are presented elsewhere [9]. Fatigue testing was conducted on an Instron servo-hydraulic closed loop automated test system utilizing a Digital Equipment Corporation PDP 1 I series minicomputer for both data acquisition and machine control.…”

The near threshold fatigue behavior of a nickel base superalloy and a wrought 2024 aluminum alloy is examined as a function of specimen geometry. Experimental results revealed that for a given value of AK in Region I, crack growth rates were observed to increase as the specimen loading became more symmetric with respect to the load line. Compact tension type specimens exhibited lower crack growth rates than the more symmetrically loaded center cracked tension specimens. Consideration of the observed discrepancies is given in terms of the near field crack tip stress distribution and deformation behavior of the material affecting crack advance.

“…An important aspect of fracture resistance is that it may vary as the crack grows such that ‫ܩ‬ is a function of the crack growth ∆ܽ [37]. Among the different experimental technics developed over the years to quantify the fracture toughness of materials, the compliance method has been successfully applied to fiber-reinforced polymer composites [36][37][38][39][40]. Early in the sixties, Sih et al…”

“…The compliance ‫ܥ‬ is defined by the slope of the load-displacement curve which is usually linear [36][37][38][39][40]. Indeed, the use of LEFM requires a linear load-displacement behaviour and very localized plastic deformation at the crack tip.…”

“…In this work, a new data reduction scheme relying on the compliance method was used. This method has been successfully implemented on the compact tension (CT) specimens and double cantilever beams (DCBs) . To evaluate the SIF following the mentioned method, the free stress, dead zone concept was thereby considered…”

This paper presents a study on stress dead zone implications and its characterization with uniaxial tensile testing on MT polycarbonate plate specimens. To obtain the experimental solution, digital image correlation (DIC) is used. Numerically, based on LEFM, the problem is solved using advanced discretization techniques, finite element, and meshless methods. Considering stress dead zone notion, it aims to determine alternative analytical solution of the SIF. Thus, the compliance method is adopted, which is associated with the specimen's dead zone region that does not involve the cracking resistance. Hence, LEFM formulations complying with strain energy release rate criterion are assumed. A proper comparison is made amongst results obtained from all theoretical, experimental, and numerical analyses. Furthermore, this work focuses on the variational fields' evaluation and, in particular, verification on the theoretical assumption of dead zone characteristics. The obtained results support adopted methodologies and are encouragingly robust and cost‐effective.
