The initial material cost of structural stainless steel is about four times that of structural carbon steel, due largely to the expense of the alloying elements and the relatively low volume of production. Given broadly similar structural performance, additional areas of benefit need to be identified and exploited in order to establish stainless steel as a viable alternative material for constr...

BACKGROUND Several mapping algorithms have been published with the EORTC-QLQ-C30 for estimating EQ-5D-3L utilities. However, none are available with EQ-5D-5L. Moreover, a comparison between mapping algorithms in the same set of patients has not been performed for these two instruments simultaneously. In this prospective data set of 100 non-small cell lung cancer (NSCLC) patients, we investigate...

AE monitoring from various types of stress corrosion cracking (SCC) has been conducted for the past 15 years in our laboratory. This paper discusses AE results of active-path dissolution-type SCC of austenitic stainless steel in chloride solution and fused salt, fluoride and polythionic acid solutions, brass in ammonia (Mattosson's solution), and carbon steels in nitrite solution. Transgranular...

the unique properties of air-cooled bainitic steels have been described. a series of mn containing air-cooled bainitic steels invented by authors is presented in this paper: including low carbon granular bainitic steels, low carbon grain-boundary allotriomorphic ferrite/granular bainite duplex steels, medium and medium high carbon bainite/martensite duplex steel, and low carbon carbide free bai...

Oil and gas pipelines manufactured from API-5L Grade X65 steel are generally subjected to cyclic loading their internal surfaces frequently exposed corrosive sour fluids. Exposure of these environments often leads localized corrosion (pitting) decreased fatigue life. Corrosion pits geometrical discontinuities that may promote cracking by acting as stress raisers. In order optimize asset inspect...

Title of Document: IMPROVED PROBABILISTIC LIFE ESTIMATION IN ENGINEERING STRUCTURES: MODELING MULTI-SITE FATIGUE CRACKING Abdallah (Moh’d AR.) (Sh. M.) Al Tamimi, PhD, 2014 Directed By: Minta Martin Professor of Engineering, Mohammad Modarres, Reliability engineering The purpose of this paper is to investigate the effect of fatigue, in the presence of neighboring cracks, and to integrate that i...
