Residual strength testing in pultruded FRP material under a variety of temperature cycles and values

Failure analysis using acoustic and energy emission assessment of fibre reinforced polymer material performance under severe conditions

“…Table 5 provides the experimental results carried out in each scenario and the coefficient of variation (CV). Based on the experimental results quantified in Table 5 equations ( 4) and (5) were developed 15 to predict the residual strength in the samples as a function of the number of cycles and the peak temperature. These experimental equations were then used to calibrate the FE model.…”

“…A numerical simulation as such can be used to analyse micro-mechanical behaviour of the sample before, during and after the collapse. The same approach has been previously employed 15 to predict reductions of strength in Glass Fiber Reinforced Polymer (GFRP) samples subjected to thermal loading.…”

“…The scenarios simulations are similar to these previously investigated in research literature. 15…”

“…universal testing machine (UTM) and finite element (FE) simulation were employed to investigate the final compressive capacity of the material. 15 In the current study, the effects of temperature peaks and thermal cycles on the failure mechanism of this material are now investigated. AE analysis and compressive tests have been applied in order to provide a more comprehensive understanding of the modes of failure and the process of collapse.…”

The use of composite materials in the device technology of bored piles in the casing

“…Наполнитель выполняет армирующую функцию и обеспечивает требуемую прочность. Полиэфирная смола придает материалу монолитность, способствует эффективному использованию прочности стекловолокна и распределению усилий между волокнами, защищает стекловолокно от агрессивных сред [7][8][9][10][11][12][13][14]. Уникальность стеклопластика в сравнении с любым другим материалом, применяемым в качестве обсадных труб, заключается в возможном сочетании свойств, которое позволит создавать буронабивные сваи с повышенными прочностными характеристиками.…”
