the objective of this paper is to present a new method for protecting the lives of residents in catastrophic earthquake failures of unreinforced masonry buildings by introducing some safe rooms within the buildings. the main idea is that occupants can seek refuge within the safe rooms as soon as the earthquake ground motions are felt. the information obtained from the historical ground motions ...

In this paper, the analysis of engine mounting structures that will be applied to electric vehicles is conducted. The structure subjected static loading from mounted components assembly, including assembly gearbox, motor, and corresponding brackets. arrangement, HSLA material mostly used general structural steel such as AISI 4130 also used. This study aims evaluate existing design so further op...

INTRODUCTION White Structure Flaking (WSF) is a type of surface damage responsible for some early failures in wind turbine gearbox bearings. WSF has been associated with microstructural changes registered close to the damaged surface that appear to be white after etching, hence the name White Etching Areas (WEAs). Local hydrogen liberation from lubricants [2] and adiabatic shear bands [3] have...

A holistic approach to diagnose the occurrence of cracking on HSLA steel slabs and propose countermeasures prevent them is presented. The consisted plant monitoring, including direct temperature measurements in strand with pyrometers. Extensive characterization was performed via thermo-mechanical tests microscopy techniques which revealed combination Widmanstätten ferrite, acicular ferrite seco...
