Fracture analysis of orthotropic cracked media is investigated by applying the recently developed extended isogeometric analysis (XIGA) (Ghorashi et al., 2012) using the T-spline basis functions. The signed distance function and orthotropic crack tip enrichment functions are adopted for extrinsically enriching the conventional isogeometric analysis approximation for representation of strong dis...

Feeding shelled corn as the primary supplement in cracked dry form or ground high moisture form to grazing cows was studied in an experiment using 32 cows in late lactation. Each of the two forms of corn accounted for 74.7% of the concentrate supplement, which was fed at 9 kg/d (DM). The experiment was 13 wk, during which cows grazed permanent native pasture containing mostly grasses and some c...

Every practice has patients who complain of cold sensitivity and pain on biting while showing no obvious signs of irreversible pulpitis. After loading each cusp and fossa in a symptomatic quadrant and ruling out pulp and periodontal pathology, definitive treatment can be performed to alleviate the patient's symptoms in a consistent, conservative manner using esthetic computer-aided design/compu...

fly's compound eye. Unlike many genetically identified proteins in this system, which are enzymes in the phos-Mayo Foundation Rochester, Minnesota 55905 phatidylinositol pathway, TRP and TRPL were originally presumed to be ion channels based on their putative It takes only one close look at a housefly to tell you six transmembrane-spanning topology and the phenotype of the associated trp mutant...

An informal argument shows that common knowledge of rationality implies the iterative elimination of strongly dominated strategies. Rationality here means that players do not play strategies that are strongly dominated relative to their knowledge. We formalize and prove this claim. When by rationality we mean that players do not play strategies that are weakly dominated relative to their knowle...

Middle-gate is located in Hasankeyf, Batman dating back to 1800 BC and is one of the important historical structures in Turkey. The ancient structure has suffered major structural cracks due to aging as well as lateral pressure of a cracked rock which is predicted to be about 100 tons. The existing support system was found to be inadequate to support the load especially after a recent rock fall...

The mechanical behavior of multicracks under compression has become a very important project in the field of fracture mechanics and rock mechanics. In this paper, experimental and numerical studies on the fracture property of three collinear cracks under compression were implemented. The specimens were a square concrete plate, and the cracks were made by a very thin film. The tests were conduct...

The work involves develops attended by a numerical execution of the eXtend Finite Element Method premises a measurement by the fracture process cracked so many cracked plates an application will be processed for the calculation of the stress intensity factor SIF. In the first we give in statically part the distribution of stress, displacement field and strain of composite plate in two cases unc...

This work presents a real life experiment of implementing an artificial intelligence model for detecting sub-millimeter cracks in metallic surfaces on a dataset obtained from a waveguide sensor loaded with metamaterial elements. Crack detection using microwave sensors is typically based on human observation of change in the sensor's signal (pattern) depicted on a high-resolution screen of the t...

A method for the identification of multiple cracks based on Discrete Wavelet Transform is presented. The analysis is provided on beams made of polymeric laminate. The estimation of the crack locations is based on the evaluation of natural modal shapes of pre-cracked beams. The modal shapes were estimated experimentally using laser Doppler vibrometry. The dynamic response of multi-cracked beams ...
