This paper presents a low cycle fatigue life curve by simulating a crack in a cover plate welded moment connection. Initiation of ductile fracture in steel is controlled by growth and coalescence of micro-voids. This research used a numerical method using finite element modeling and simulation of ductile crack initiation by a micromechanical model. Therefore, a finite element model of a cover p...

One of the important aspects highway design is aggregates. Aggregates strength and consistency has an effect on pavement structure’s overall performance. The base material near site construction doesn’t always match requirements carrying quality aggregate raises cost construction. Stabilizing agents such as asphalt cement, lime, fly ash were used to improve these materials in order make greater...

A B S T R A C T The fracture of bone is a health concern of increasing significance as the population ages. It is therefore of importance to understand the mechanics and mechanisms of how bone fails, both from a perspective of outright (catastrophic) fracture and from delayed/time-dependent (subcritical) cracking. To address this need, there have been many in vitro studies to date that have att...

Recently, bitumen pavements have been widely used for road paving. Various scholars modified in paving to improve pavement performance, thus increasing the service life. In this study, Sasobit, XT-W3, and Evotherm were selected as warm-mix various investigations including conventional Brookfield rotational viscosity, dynamic shear rheology, Marshall stability, high-temperature rutting, water lo...

An overview is given of the anomalous behavior of some metals, in particular Fe and Cr, in acidic aqueous solutions during anodic dissolution. The anomaly is recognizable by the fact that during anodic dissolution more material dissolves than would be expected from the Faraday law with the use of the expected valence of the formed ions. Mechanical disintegration, gas bubble blocking, hydrogen e...

The treatment and repair strategies for reflective fatigue cracking that initiate at the pavement surface (i.e., top-down cracking) bottom of asphalt concrete layer bottom-up are noticeably different. However, management engineers facing difficulties in identifying these cracks field because they usually appear visually identical patterns. objective this study was to develop artificial neural n...

Abstract The fracture resistance of different advanced high-strength steel (AHSS) sheets for automotive applications is investigated through conventional tensile tests, toughness measurements, and hole expansion tests. Different fracture-related parameters, such as the true strain (TFS), thickness (TTS), at crack initiation ( w e i ), specific essential work ratio (HER), are assessed. ) shown t...

The present study investigated the hydrogen-related fatigue fracture under various test frequencies in low-carbon martensitic steel. In hydrogen-charged specimen, although number of cycles to failure decreased with decreasing frequency, time was almost same regardless frequency. Observation surface revealed that transgranular a main component uncharged while intergranular often observed especia...

This project examines the nature of password cracking and modern applications. Several applications for different platforms are studied. Different methods of cracking are explained, including dictionary attack, brute force, and rainbow tables. Password cracking across different mediums is examined. Hashing and how it affects password cracking is discussed. An implementation of two hash-based pa...

current article describes application of zeolites in fluid catalytic cracking (fcc). the use of several zeolitic additives for the production light olefins and reduction of pollutants is described. application of zeolites as fluid catalytic cracking (fcc) catalysts and additives due to the presence of active acid sites in the zeolite framework  increase the formation of desired cracking product...
