this research was conducted in order to evaluate fatigue behavior of asphalt mixes containing electric arc furnace (eaf) steel slag. after initial evaluation of the properties of eaf steel slag using x-ray diffraction (xrd) and scanning electric microscope (sem), six sets of laboratory mixtures were prepared. each set were treated replacing various portions of limestone aggregates of the mix wi...

In this paper a new method to determine the fracture properties and strain energy release rate for Carbon- Polyester composite has been introduced.  Fracture characteristics such as critical stress intensity factor and critical strain energy release rate for mode I, mode II and mixed mode loading were determined using Arcan type specimen. 130 layers of carbon fiber polyester woven composite wit...

The growth of slant cracks by fretting fatigue of a half plane in contact with a flat rounded pad was studied. The mode I and mode II stress intensity factors for cracks of various lengths and directions were calculated using the semi-analytical method of the distribution of dislocations, and their cumulative effect on the crack growth was investigated using the strain energy density criterion....

In inclined U-notches, the mixed mode (I + II) loading occurs and the mode ratio can be increased by varying the notch angle. In this paper, the effect of the inclined U-notch geometry, i.e. the notch depth, the notch angle, the notch root radius, and the position of the notch with respect to supports, on the mode ratio (KII/KI) have been studied. Three-point bending and plane strain condition ...

The subject of structural health monitoring and damage identification of structures at the earliest possible stage has been a noteworthy topic for researchers in the last years. Modal strain energy (MSE) based index is one of the efficient methods which are commonly used for detecting damage in structures. It is also more effective and economical to employ some methods for reducing the degrees ...

The gene for phosphoryl ase b kinase, a skeletal muscle enzyme, has been located on the X chromo some of mice. The inheritance of the enzyme through two generations from original matings between one inbred strain of mice, the I, which lacks the enzyme, and another strain, the C(57,) follows the classical Mendelian pattern.
