the effect of wheat-sorghum flour ratio (0, 25, 50, 75 and 100%) on viscoelastic and farinographic behaviour of dough was investigated. constants of peleg - normand model and the stress relaxation (% sr) was calculated for the variables and the correlation between farinograph characteristics and stress relaxation test parameters were evaluated. the results showed that with increasing the ratio ...

in this paper, the experimental method of caustics and its application to stress field and related studies in fracture mechanics is described. theocaris [1,2,3] has used the optical method of caustics to study stress intensity factors and the stress field around crack tips, in cracked transparent plates. many other researchers have also used this method to obtain stress intensity factors for di...

First row rotating blades of four axial-flow compressors were prematurely fractured. Previous investigations showed that the site atmosphere contains corrosive compounds which lead to an increase in possibility of pitting on the blades. It was also revealed that the crack was originated from two corrosion pits. Thus, this work is conducted to ascertain which of fatigue or stress corrosion crack...

Two visual world experiments tested the hypothesis that expectations based on preceding prosody influence the perception of suprasegmental cues to lexical stress. Experiment 1 showed that phonemically overlapping words with different initial stress patterns compete for recognition. Experiment 2 further demonstrated that fundamental frequency and syllable timing patterns across material precedin...

When granular material is modeled as a continuum, plastic constitutive behavior is often assumed. The use of plasticity amounts to replacing a complicated micromechanical system by its average behavior. Recent experiments have shown that, at least for small-scale systems, stress fluctuations may be of the same order, or even much larger, than average stresses. In this paper a first generation o...
