Abstract

In this study, we attempt to have numerical and software analysis of behavior, deformation and strain caused by local dental loads (dent) in GFRP tanks. The load-displacement and the load- Strain diagrams in experimental and software conditions have also been analyzed, compared and evaluated. The research can be used in oil company projects, water organization and different types of tanks which are exposed to local loads. the experimental and theoretical researches on GFRP tubes and tanks under dental loads and concluded that all samples have linear behavior from beginning to end and proceed with the same slope which is due to the behavior of the GFRP materials (Zarrin, 2018). To test the behavior of experimental specimen under the influence of Dent’s load, wedge is used. In another studies different types of dental loads are applied to the tanks like Dome-shaped dental load, Circular dental load and Rectangular dental load (Jajo, 2014). To understand the importance and necessity of research, we must first study the dental load, how it is applied to the tanks, the dangers of applying it to the tanks and the ways of resistance against these loads.
