The creep test under the static loading, that allows to determine rheological properties of asphalt based on curve, is most effective nowadays. Applied loads are non-destructive and allow observe course strain after load. can be carried out compressing, shearing, bending as well triaxial test, depends applied apparatus implementing different intensity [1, 2, 3, 4, 5, 6]. Based stress specified....

ABSTRACT- Mechanical damage degrades fruit quality in the chain from production to the consumption. Damage is due to static, impact and vibration loads during processes such as harvesting, transportation, sorting and bulk storage. In the present study finite element (FE) models were used to simulate the process of static bruising for apple fruits by contact of the fruit with a hard surface. Thr...

AIMS Three-dimensional (3D)-echocardiography speckle imaging allows the evaluation of frame-by-frame strain and volume changes simultaneously. The aim of the present investigation was to describe the strain-volume combined assessment in different patterns of cardiac remodelling. METHODS AND RESULTS Fifty patients received a 3D acquisition. Patients were classified as follows: healthy subjects...

To investigate the hot deformation behavior of 17-7 PH stainless steel, hot compression tests were carried out at the temperatures of 950, 1050 and 1150 oC and strain rates of 0.001 s-1 to 0.1 s-1. Accordingly, the hot working behavior was studied by the analyses of flow stress curves, work hardening rate versus stress curves, exponent- type constitutive equations and deformed microstructures. ...

Strain has been widely used to manipulate the properties of various kinds of materials, such as ferroelectrics, semiconductors, superconductors, magnetic materials, and "strain engineering" has become a very active field. For strain-based information storage, the non-volatile strain is very useful and highly desired. However, in most cases, the strain induced by converse piezoelectric effect is...

Products from Xanthoceras sorbifolium Bunge seed have gained extensive attention for various applications, especially in the fields of edible oils and industrial applications. In order to study kernel mechanical–structural behavior oil yield mechanisms during extrusion, we set up a self-developed texture analyzer with situ microscope observation. Test results indicated that pressing energy show...

The mean stress effect on the fatigue life of 304L austenitic steel was evaluated at 300 °C in air and pressurized water reactor (PWR) environments. Uniaxial tests were performed strain-control load-control modes, with zero a positive 50 MPa. A specific procedure used for strain-controlled experiments to maintain strain amplitude constant. data indicate that application decreases given PWR also...

This paper reports a study of the reflectance optical sensors based on graphene under uniform strain. Assuming layer is surrounded by two different semi-infinite dielectric media, generalized Fresnel coefficients are derived as function usual quantities (e.g., constants, incident angles, and strain) anisotropic conductivity. The strain not only changes electronic band structure but also can be ...
