The bridge would be able to remain open during this time, limiting traffic to one lane in some cases. Fatigued welds would be strengthened using various methods, such as shot peening and laser peening (Bennett, Matamoros, Barett-Gonzalez, & Rolfe, 2014, p.8). 2.4 Alternative C Under Alternative C a new bridge would be built adjacent to the existing bridge. The new bridge would replicate the existing Yaquina Bay Bridge to provide
This is another property which relates the fatigue to tensile property of any material. It can be defined as the ratio of the endurance limit (Se) to the ultimate strength (Su) of the material of any structure. The value of fatigue ratio ranges from 0.25 to 0.60. It’s value solely depends upon the type of the material. Facture Theory Fatigue failure can be divided in three parts i.e. Crack initiation, Crack propagation and Final rupture. • Crack initiation It is the most important and the most complex
CONNECTING ROD A connecting rod is an engine component that transfers motion from the piston to the crankshaft and functions as a lever arm. All connecting rods for automotive use need to be lightweight but strong enough to withstand and transmit the thrust from the pistons to an engine's crankshaft. Holes on both ends of a connecting rod are machined to perfectly connect to pistons and the crankshaft. Connecting rods are available in a variety of sizes and materials ideal for certain situations
Chapter 1 INTRODUCTION The connecting rod or con rod connects the piston to the crank or crank shaft. Together with the crank, they form a simple mechanism that converts reciprocating motion into rotating motion. As a connecting rod is rigid, it may transmit either a push or a pull and so the rod may rotate the crank through both halves of a revolution, i.e. piston pushing and piston pulling. In modern automotive internal combustion engines, the connecting rods are most usually made of steel for
a. Introduction In the quality assurance of machine components the so-called finishing and super-finishing processes have important roles. During recent years, the post-machining cold forming methods such as burnishing, shot peening, etc., have occupied a very important place in industry, because they are reported to induce compressive residual stresses on the work piece surface, which in turn, results in improvement of tribological properties such as wear resistance, fatigue life, corrosion resistance
