Abstract:
The present study aims at investigating the Code IS 456 specified flexure strengths of concrete. This investigation involved carrying out a split tensile test on cubes. The design mix calculations for M20, M25, M30, M40, M50 and M60 were done. Steel fibers were used to improve the resistance of fracture and tensile strength of concrete by its volume percentage of 1%, 2% and 3% for all the grades. The testwas carried out on the universal testing machine using billets to apply point load on exactly mid of the cube. It was observed that the code specified flexure strength is a conservative estima

Abstract:
Glass Fiber Reinforced Polymer (GFRP) bars are used as reinforcement for structural concrete, especially in cases where corrosion of traditional steel reinforcement is a problem. The tensile strength of these reinforcing bars is the primary characteristic on which the design of concrete members reinforced with GFRP bars relies. Determination of the tensile strength of the bars using a direct tensile test is a time and resource-intensive task and therefore is not routinely conducted for quality control. The tensile strength can also be measured from flexure tests, which are much simpler than di

Abstract:
In this study, the nanophased epoxy with 2 wt.% clay was utilized in a vacuum assisted resin transfer molding (VARTM) set up with carbon fabric to fabricate laminated composites. The effectiveness of clay addition on mechanical properties of composites has been evaluated by tensile, flexural and fatigue test. The tensile and flexural strengths improved by 5.7% and 13.5%, respectively as compared to the neat composite. The fatigue strength was also improved significantly. Based on the experimental result, a linear damage model combined with the Weibull distribution function has been established

Abstract:
The calculation of the effective volume and/or effective area is a key step in estimating the reliability of ceramic component life cycles. Most common tests performed to assess the strength of components made from ceramics are bend bar specimens tested in three-point and four-point flexure, C-ring and O-ring specimens under diametral compressive or tensile loads, and biaxial ring-on-ring specimens. ASTM closed form solutions [1] for the effective volume and area exist for specimen geometries based on classical theories with underlying assumptions. In general, the closed form expressions are v

A systematic study has been conducted on processing and characterizing of carbon fiber reinforced epoxy polymer (CFRP) composites to enhance their properties through the optimization of graphene nanoplatelet (GNP). GNP having a two dimensional structure is composed of several layers of graphite nanocrystals stacked together. GNP is expected to provide better reinforcing effect in polymer matrix composites as a nanofiller along with greatly improved mechanical and thermal properties due to its planar structure and ultrahigh aspect ratio. GNP is also considered to be the novel nanofiller due to

Abstract:
Abstract Delamination is a common failure mode observed in ceramic matrix composites (CMCs) and occurs as a result of applied interlaminar tensile and shear stresses exceeding the interlaminar strength. As CMCs are further implemented into aero engines the need to understand their interlaminar failure becomes increasingly important. While significant contributions have been made toward understanding the mode I fracture toughness of CMCs, limited work exists on mode II. Several test methods for measuring the mode II fracture toughness have been proposed in literature, namely the end-notched fle

Abstract:
The research discussed in this progress report has been proposed to study the interface shear transfer in applications for partial-depth concrete repairs and for topping applications on precast elements. This research comprises two phases of laboratory testing. Phase 1 was developed to study the (local) interface bond strength of slab specimens through direct shear tests and direct tensile pull-off tests. Phase 2 comprises flexural tests on beam specimens to assess interface shear strength under combined bending and shear.

Abstract:
Although current manufacturing methods result in highly reliable welds in ERW pipe, occasional small bond line defects, difficult to detect with present nondestructive test techniques, still are found. The development of improved inspection techniques to permit the detection of such small defects is a difficult undertaking. An Alternative approach toward increasing the reliability of ERW pipe is to insure that the weld region is able to tolerate the presence of any undetected defects without failure, that is, to insure that the weld has adequate ductility.

Abstract:
There have been a number of notable girth weld failures in newly constructed pipelines in North America, Asia, and South America. The primary contributors to the North America incidents have been identified as (1) weld strength undermatching, (2) heat-affected zone softening, and (3) elevated stress-strain in the affected girth welds. This project is a continuation of previous PRCI supported work and JIP with a particular focus on addressing the first two contributors through enhanced girth welding procedure qualification.

Abstract:
Current design of pipelines calls for overmatching weld metal tensile strength, forcing deformation to occur in the base material and not in the weld. If straining of the weld metal were to occur, higher levels of weld metal toughness would be required to prevent fracture initiation from pre-existing defects. There are three known issues related to the Submerged Arc Welding (SAW) double jointing of pipeline steels: - Consistently achieving weld metal strength and toughness requirements. - Heat affected zone (HAZ) softening of the base material. - Lack of an accepted test protocol for the entir
