The purpose of the software is to streamline the process to obtain fracture toughness from double cantilever beam (DCB) tests. The program analyzes a series of images, looking for the crack …

Automatic crack tracking in DCB specimens via edge detection software and an overhead CCD camera is simple, reliable, and accurate. Automatic tracking provides a more continuous crack …

The purpose of the software is to streamline the process to obtain fracture toughness from double cantilever beam (DCB) tests. The program analyzes a series of images, looking for the crack tip.

2020年12月1日 · In this work, we propose an approach to use full field displacement maps, provided by DIC, to measure the crack length and crack’s growth onset and propagation, thus …

2019年1月1日 · The method combines the virtual crack closure technique (VCCT) with the cohesive zone modelling (CZM) on the finite element basis to take into account the …

Kanninen (1973) presented an analytical model for a DCB where the upper arm was modelled as a Euler–Bernoulli beam on elastic foundation (Winkler model), allowing for relative …

A set of methods for evaluating the resistance curve (R-curve) behaviour of double cantilever beam (DCB) and end notch flexure (ENF) test specimens. Unlike traditional methods, these …

The tapered double cantilever beam (TDCB) test geometry (Fig. 6.18) ensures that the change in compliance is independent of the crack length (i.e. constant compliance). It is used for Mode I …

Several benchmark tests regarding irregular discretizations are performed, and the results indicate that the CE method is capable of naturally capturing complicated crack patterns in …

The Double Cantilever Beam shown below is cracked at the center. This problem uses an imported model, already meshed, and computes fracture parameters (energy release rates) …
