Abstract The famous bifurcation analysis performed by Flügge on compressed thin-walled cylinders is based a series of simplifying assumptions, which allow to obtain the landscape, together with explicit expressions for limit behaviours: surface instability, wrinkling, and Euler rod buckling. most severe assumption introduced use an incremental constitutive equation, does not follow from any non...

Intracranial aneurysms (IA) are dilations of the cerebral arteries and, in most cases, have no symptoms. However, it is a very serious pathology, with high mortality rate after rupture. Several studies been focused only on hemodynamics flow within IA. besides effect flow, development and rupture IA also associated combination other factors such as wall mechanical behavior. Thus, objective this ...

In this current research, a commercial aircraft metallic leading edge structurally reinforced with Y-shaped and V-shaped plate system is numerically examined to investigate the effectiveness of such reinforcements against soft impacts, more commonly known as bird strikes in aviation industry. A non-linear finite element code Ansys Explicit adopted run virtual test cases. The computational model...

Abstract NPTs have vast applications because of no tyre puncture, need for air pressure, low rolling resistance, and also higher flexibility design recyclability. In this research work, different structures polyurethane (PU) spokes been designed analyzed under radial loading conditions which include like honeycomb with varying cell angles, simple spoke, trapezoid type by keeping in view that th...

Recently, data-driven approaches in the field of material modeling have gained significant attention. A major advantage these is direct integration experimental results into models. Nevertheless, artificial neural networks (ANNs) are especially challenging to interpret from a physical point view, since internal processes ANNs difficult understand. In this work new automatic method for generatio...

Abstract In additive manufacturing, also called 3-D printing, one of widely used materials is polylactide thermoplastic polymer (PLA) by means the fused deposition modeling. For weight reduction purposes, infill density an often feature in slicing for printing. We aim at investigating effect on mechanical properties structures. Therefore, we demonstrate how to prepare tensile specimens and test...

In the current research, a three-dimensional finite element model was considered to predict the mechanical behavior of Single Wall (SWCNTs) and Multi Wall Carbon Nanotubes (MWCNTs). Assuming the nonlinear elastic behavior of C-C bond in large strains, hyperelastic models were considered. Literature review revealed that the material parameters of the hyperelastic models have been determined from...

In this paper, nonlinear analytical solution of pressurized thick cylindrical shells with variable thickness made of hyperelastic materials is presented. The governing equilibrium equations for the cylindrical shell with variable thickness under non-uniform internal pressure are derived based on first-order shear deformation theory (FSDT). The shell is assumed to be made of isotropic and homoge...
