In this study, the behavior of a composite lattice cylindrical shell is investigated in the buckling deforming. Also, the distribution of shell buckling response and the stress field is studied after making some defects on the ribs.Therefore using ANSYS software, a 3D finite element model of the shell has been created for the analysis. Material properties and geometrical data of the shell are o...

This work studies the rate-dependent mechanical behavior of filament-wound fiber-reinforced polymer (FRP) composite pipes. Commercially available tubes with a filament winding angle ±55° were tested under cyclic axial compression for four loading rates. Stress relaxation constant strain was observed as well dependence stress on rate. A novel modeling methodology is presented to capture nonlinea...

This study aims to determine the optimal 3D Printer filament extruder machine design, design of components for production, single screw used production. The research method is creating flow chart, result calculation diameter 1.77 mm, by measuring taking a 2 meters long sample be measured every 10 cm. most influential in this are diameter, length extruder, winding process, production capacity an...
