Polypropylene fibers are added to concrete improve the toughness of material. Manufactured sand and fly ash with high content used reduce impact on environment cost. The response surface method (RSM) was design test study mechanical bending properties polypropylene-fiber-reinforced high-performance (PPFHPC). Three process variables, including polypropylene fiber (1%, 1.5%, 2%), (45%, 60%, 75%),...

Today’s demand for environmentally friendly and energy-efficient solutions to the construction industry has driven researchers match natural resources with traditional technics develop new building technologies. However, there are literature limitations about correlation of fiber-matrix interface failure fibers in mortar plates, which hinders advances understanding mechanical properties these c...

Flexural strength, hardness, and fracture toughness are the basic mechanical properties of ceramic materials. Manufacturers widely use this set to ensure durability products. However, many factors, such as chemical phase compositions, sintering temperature, average grain size, density, others, affect these properties, making it challenging estimate corresponding reliability parameters correctly...

The cleavage fracture toughness of steels was mezzo-scopically analyzed on the basis of the statistical local fracture criterion approach. The statistical stress criterion at the crack tip region suggests that the cleavage fracture toughness in steels can be described as a function of the yield stress, the cleavage fracture stress, and other mechanical properties of the materials. Formulation o...

High-strength all-ceramic systems for fixed partial dentures (FPDs) is gaining popularity as an alternative to the well established metal-ceramic FPDs. Several new framework materials and technique such as lithium disilicate, aluminum oxide and yttrium tetragonal zirconia polycrystal have been developed with improved strength, marginal discrepancy and esthetics. Since not every all-ceramic syst...

Due to the high risk of common traffic electric poles, use glass fiber reinforced polymer (GFRP) material in poles has become essential due its excellent advantages such as strength weight ratio, corrosion resistance, and electrical insulation, which keeps people safe. To reduce accidental effect street lighting on humans, generated energy during collision must be absorbed. Experimental numeric...
