In this research, strain-sensing and damage-sensing functional properties of cement composites have been studied on a conventional reinforced concrete (RC) beam. Carbon nanofiber (CNFCC) and fiber (CFCC) cement composites were used as sensors on a 4 m long RC beam. Different casting conditions (in situ or attached), service location (under tension or compression) and electrical contacts (embedd...

In recent years, the authors have developed a dedicated strain gage (hereafter referred to as K-value gage) and an analysis method that can analyze stress intensity factor of crack with single element. The single-element K value obtain opening mode simulated within ±5% theoretical value. this study, using gage, was inserted into one side edge strip attempt made when out-of-plane bending load ap...

In this study, the static safety factor and fatigue life of fastening devices an agricultural by-product collector were evaluated under hard flat ground driving conditions. The strain gage-based measurement system was constructed, gage attached on highest stress spot derived from structural analysis. calculated using measured values by converting it into data. two operating conditions are consi...

Characterization of all-printed strain gages to assess their suitability for structural state monitoring of large structures is presented. Strain sensor response, transverse strain sensitivity and long-term reliability are key performance parameters of printed strain sensors on flexible substrates. These key performance parameters are evaluated for inkjet and screen printed strain sensors on po...

The purpose of this study was to evaluate cuspal flexure in posterior primary teeth following restoration with three different materials. Twelve primary second molars were obtained. A precision strain gage was attached to the buccal surface of each tooth and balanced at zero. The teeth were mounted and then loaded with a 10 kg force; the strain appearing on the strain gage indicator was recorde...

Cement composites with hybrid conductive fillers carbon nanotubes (CNT) and graphite products (GP), have been tested as strain sensors under varying temperatures (0 °C–60 °C), moisture conditions (0%–100% saturation degree (SD)). pastes 1% CNT 5% GP (purified expanded graphite) presented resistivity values between 50 75 Ohm·cm, their sensing response was observed to be independent of the loadin...

Measuring the forces that work during machining has been being concerned by researchers for years. There are three main in turning: thrust force, axial and radial force. Thus, feeding force measurement is needed machine manufacturing. This research attempts to develop method through using strain gauge sensor. The aim of this find out influence parameter towards used experimental with design exp...
