An experimentally validated numerical method for investigating the air blast response of basalt composite plates

Abstract

Nonlinear air blast response of basalt composite plates is analysed by using a generalized differential quadrature (GDQ) method, which requires less solution time and decreases the complexity compared to finite element method. A test environment that contains a shock tube is designed and set to experiment on the transient response of blast loaded laminated plates. Experimental and numerical results show a good agreement in terms of displacement, strain and acceleration versus time. The responses of glass/epoxy, Kevlar/epoxy and carbon/epoxy composite plates are also investigated by using GDQ method and the results are compared with the basalt/epoxy composite plate and discussed.

Notice of Retraction: Perspective and Prediction of the Rule of High Temperature Melting of SiO₂ via Visual Analysis

“…The results show that the surface emissivity of the slag particles is 0.89 when the surface temperature is 1402 • C. With the increasing awareness of energy conservation and emission reduction, many scholars gradually realize the broad prospect of blast furnace slag preparation of slag cotton [19], [20]. They explore the new technology of direct fibrosis of blast furnace slag preparation of slag cotton, and have made some achievements [21]- [29]. Basalt cotton was prepared by 60% blast furnace slag and 40% basalt, and its feasibility was verified [21].…”

Performance analysis of fiber-reinforced polypropylene composite laminates under quasi-static and super-sonic shock loading conditions for impact application

“…The radius of curvature has significant effect on mode of failure. Susler et al 19 numerically analyzed air-blast response of basalt composites. Non-linear air blast of basalt composites was studied by generalized differential quadrature (GDQ) and compared by finite element method (FEM).…”

Effects of Volume of Carbon Nanotubes on the Angled Ballistic Impact for Carbon Kevlar Hybrid Fabrics

“…Eventually safe, durable materials, but expensive Kevlar/ Carbon Fiber Hybrid Fabrics with CNT epoxy resin are studied in the current research to normal and oblique impact resistance. Carbon fibers, despite their high price, are predominantly used for ballistic protection under rifle bullet threats [15][16][17][18]. Although commercial monolithic carbon fiber plates could be manufactured to a large thickness, they may not meet the design needs for certain thickness and multiple thinner plates, which are used to meet design specifications.…”

“…Although commercial monolithic carbon fiber plates could be manufactured to a large thickness, they may not meet the design needs for certain thickness and multiple thinner plates, which are used to meet design specifications. In addition, multi-layer plates can provide flexibility to users in terms of mobility and maintenance [17][18][19]. For this reason, most experimental studies as well as those in the published works relating to the ballistic performance of carbon fiber plates focus on replacing monolithic plates with layered plates of the same thickness.…”
