Understanding the effect on the materials mechanical properties from the perspective of interfacial interaction between the filler and the polymer matrix has become an important criterion in polymer nanocomposites field. Cellulose nanocrystals (CNCs) are renewable materials that can be extracted from natural sources, such as wood, cotton, and tunicates. In addition, CNCs have the characteristic...

Objectives/Goals This project was designed to determine how varying the amount of a specific ingredient that constitute a bioplastic mixture can affect tensile strength. I hypothesized that if more glycerin is added to a mixture of cornstarch, water, vinegar, and glycerin, then a bioplastic with increased tensile strength and flexibility will be produced. Methods/Materials Mold, 40 bioplastics ...

Rock tensile strength (TS) is an important parameter for the initial design of engineering applications. The Brazilian (BTS) test suggested by International Society Mechanics and American Testing Materials widely used to assess TS rocks indirectly. Evaporitic rock blocks were collected from Al Ain city in United Arab Emirates. Samples tested, a database 48 samples was created. Although previous...

The present work was conducted to investigate the geotechnical properties of two meta-peridotites and meta-pyroxenites of an ultramafic complex mainly consisting of ultramafic rocks. For this purpose, microscopic studies were performed to determine the percentage of serpentinization in these rocks. In addition, a number of mechanical and physical tests were performed on collected samples with d...

During underground nuclear tests, rocks may fail by plastic yielding, which limits shear strength, or by tensile fracture, wherever maximum principal stress exceeds tensile strength. A third mode of failure exists due to friction along closed fractured surfaces. There, friction affects slipping and can thus limit stress. In this paper, we study the effect of friction on the simulated dynamic re...

Modification of soy protein film properties by heat-curing was studied. Glycerin-plasticized films were cast from alkaline aqueous solutions of soy protein isolate. Films were heated at 80 or 95°C for 2, 6, 14, or 24 h. Tensile strength (TS), elongation at break (E), moisture content (MC), water solubility (WS), water vapor permeability (WVP), and color of heated and control films were measured...

A 23 factorial experimental design has been used to quantitatively study individual and interaction effects of the nature of binder (N), concentration of binder (C) and the applied pressure (P) on two mechanical properties, namely, tensile strength (TS) and brittle fracture index (BFI), of paracetamol tablets. The factorial design was also used to study the quantitative effects of coprocessing ...
