We constructed an atomic structure model for a PANbased carbon fiber containing amorphous structures using molecular dynamics methods. It was found that basic physical properties such as crystallinity, Young’s modulus, and thermal conductivity of our model were nearly identical to those of real carbon fibers. We then obtained the tensile strength of a carbon fiber, which has no macro defects. W...

The construction industry is the largest consumer of natural resources which led to depletion of good quality natural sand (Fine aggregates). This situation led us to explore alternative materials and granular slag a waste industrial byproduct is one such material identified for utilization it as replacement of natural sand. This paper highlights upon the feasibility study for the utilization o...

In this paper we give an account of applications of quantum-mechanical (first-principles) electronic structure calculations to the problem of theoretical tensile strength in metals and intermetallics. First, we review previous as well as ongoing research on this subject. We then describe briefly the electronic structure calculational methods and simulation of the tensile test. This approach is ...

PURPOSES To assess the tensile strength of the modified 4-strand cruciate technique for obliquely lacerated tendons, and to compare the findings with the strength of transversely lacerated tendons repaired at various grasping depths. METHODS 60 porcine front foot tendons were evenly divided into 4 groups. In groups 1 to 3, tendons were transversely lacerated and repaired with grasping points ...

–A detailed investigation has done Redmud an Alluminium industrial waste product has done to study its feasibility for use in road constructions. In this study Redmud was stabilized with 2, 4, 6, 8,10and 12 percentages of lime and unconfined compressive strength, Split tensile strength and California bearing ratio tests were conducted at 1, 3, 7 and 28 days curing periods respectively. From the...

Nowadays solid propellant motors (SRMs) are widely used because of simple structure and reliability. One of the requirements in SRMs is high tensile and bonding strength of liner for integrity of grain structure and neutralizes stresses applying to motor. In this research, effect of curing agent ratio (NCO/OH) in the range of (R=0.9-1.4) on tensile strength of liner and bonding strength of line...

A high-strength Concrete structure is what everyone tries to achieve through the project. So many studies are being studied with various types of fibers. In this paper, I have used PVA fibers two different plasticizers. The main purpose study find amount plasticizer be and which feasible for proportions We casted 0.125%, 0.250%, 0.375%, 0.50% fiber in proportion weight cement. also their compre...
