The purpose of this research was to experimentally characterize the flexural and tensile characteristics of fiber-reinforced Very High-Strength Concrete (VHSC) panels. The panels were made with a unique mix of cementitous materials achieving compressive strength of 26,000 psi (180 MPa) or greater. VHSC panels were reinforced with polypropylene fibers of 1 inch (25.4 mm) in length and Polyvinyl ...
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 ...
stress relieving is a common practice among manufacturing codes for reducing the magnitude ofresidual stresses in welded, quenched, and tempered steel structures and pressure vessels. the presentwork investigates the effect of stress relieving at 480, 560, 620, and 680°c on the microstructure andmechanical properties of 20 mm astm a517 gr. b steel plate weldments produced by shielded metal arcw...
This paper investigates the effect of loading level and loading rate on the damage development and strength on the asphalt mixtures tested at three low temperatures. The current AASHTO specification for asphalt mixture low-temperature characterization consists of two tests: the indirect tensile creep (ITC) test and the indirect tensile strength (ITS). In the ITC, the load was applied until the ...
Instrumented Charpy test data can be used to obtain estimates of dynamic yield strength, by means of a well-established relationship published by W. Server in 1978. A fundamental issue in comparing measured dynamic tensile properties and Charpy-based estimations is establishing the equivalent uniaxial strain rate for an instrumented Charpy test, typically conducted at ≈ 5.5 m/s. In this investi...
Fused Deposition Modeling (FDM) is a kind of Rapid prototyping (RP) technique, which allows direct transformation of CAD files into physical models. This paper attempts to identify and study the influence of electroplating layer thickness on the mechanical strength of Acrylonitrile butadiene styrene (ABS) samples developed from the FDM process. The study is conducted on the tensile test samples...
In this study, we develop binary polypropylene (PP) composites with hexagonal boron nitride (hBN) nanoplatelets and ternary hybrids reinforced with hBN and nanohydroxyapatite (nHA). Filler hybridization is a sound approach to make novel nanocomposites with useful biological and mechanical properties. Tensile test, osteoblastic cell culture and dimethyl thiazolyl diphenyl tetrazolium (MTT) assay...
