“…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 method has been successfully implemented on the compact tension (CT) specimens 9,10,12 and double cantilever beams (DCBs). 13,14 To evaluate the SIF following the mentioned method, the free stress, dead zone concept was thereby considered. 15 Although several approaches to assess SIFs for dissimilar material behaviours are available, [16][17][18] this contribution primarily aimed at implementing an alternative analytical solution based on the compliance methodology.…”

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.

“…One that has enjoyed particular success is the J-integral developed by Rice [20], a path-independent contour integral that can be interpreted as a non-linear energy release rate. Simple closed form solutions of the J-integral have been used to obtain fracture toughness in tests such as ENF [21], ELS [22] and MMB [23], which could be good alternatives to the current data reduction methodologies.…”

The objective of this work is to define reliable test methodologies and data reduction methods to obtain comparable results among the most common mode II test methodologies: the End-Notched Flexure (ENF), the End-Load Split (ELS), the 4-point End-Notched Flexure (4ENF), and the Mixed Mode Bending (MMB) test at 100% of mode II. For this reason, an experimental test campaign consisting of the abovementioned four mode II test methods was carried out. The J-integral was implemented in the ELS, the ENF and the MMB tests and a J-integral closed form was developed and implemented for the 4ENF test. Then the J-integral was compared to the data reduction methods based on Linear Elastic Fracture Mechanics (LEFM). The results obtained from the J-integral based methods were independent from the test methodology and obtained very good agreement among the tests. In addition, from the experimental results the advantages and drawbacks of the different test procedures are analysed and discussed, concluding that the ELS test is the most suitable to measure mode II fracture toughness of adhesives.

“…A number of applications have been proposed within many scientific settings for elastic [4], hyperelastic [5], composite [6] and viscoelastic materials [7], generalized to accommodate a crack growth model [8]. The J-integral concept has now been generalized for complex loadings with coupling friction effects [9], transverse loadings [10], mixed-mode configurations [11][12], and fatigue applications [13].…”

International audienceThis paper focuses on the theoretical and numerical development of the J-integral concept for three-dimensional problems. A new integral parameter, developed for the real three-dimensional case, computes the combined energy release rate for an arbitrary crack front. A path-independent integral is verified in both the static and crack propagation cases. Generalization of the í µí°½ "#-integral toward its í µí°º % "# implementation form is performed. The efficiency of this proposed integral is then compared with a number of í µí°½ integrals available in the literature. Lastly, the paper offers a finite element implementation along with its numerical validation
