Multi-Scale Numerical Analysis of the Effect of Microstructural Features on the Mechanical Behavior of Polycrystalline Ti-6Al-4V Alloy

Fatna BENMESSAOUD, Vincent VELAY, Mohammed CHEIKH, Vanessa VIDAL, Christine BOHER & Farhad RÉZAÏ-ARIA
The present work aims to model the influence of microstructural features of Ti-6Al-4V titanium alloy on its mechanical behavior. A multi-scale approach based on crystal plasticity is considered. The elasto-viscoplastic constitutive equations of Meric-Cailletaud are modified to take into consideration the effect of the grain size by introducing the Hall-Petch relationship at the local scale. This modified model is coupled with finite element calculations under small strain assumption to simulate the monotonic mechanical behavior of...

Analytical and Numerical Studies of an Unsymmetrical Sandwich Beam – Bending, Buckling and Free Vibration

Krzysztof MAGNUCKI, Ewa MAGNUCKA-BLANDZI, Jerzy LEWIŃSKI & Szymon MILECKI
The subject of the paper is an unsymmetrical sandwich beam. The thicknesses and mechanical properties of the beam faces are different. Mathematical model of the beam is formulated based on the classical broken-line hypothesis. The equations of motions of the beam is derived on the ground of the Hamilton’s principle. Bending, buckling and free-vibration are studied in detail for exemplary unsymmetrical structure of the beam. The values of deflection, critical force and natural frequency are...

The Influence of High-Strength Bolts Stiffening on Flange Connection Behaviour

Izabela MAJOR, Maciej MAJOR & Krzysztof KULIŃSKI
Flange connections can commonly be seen in advertising board structures, which are subjected to wind loading. Depending on the structure’s geometry, additional torsion forces should be taken into account. In this paper the static behaviour of a flange connection with highstrength bolts under torsion load has been discussed. The numerical analysis concerns two cases: a flange connection subjected only to a high-strength bolts prestressing load and a flange connection subjected to both – bolts prestressing...

Approaches to the Determination of the Working Area of Parallel Robots and the Analysis of Their Geometric Characteristics

Dmitry MALYSHEV, Mikhail POSYPKIN, Larisa RYBAK & Alexander USOV
The article presents and experimentally confirms two approaches to the problem of determining the working area of parallel robots using the example of a planar robot DexTAR with two degrees of freedom. The proposed approaches are based on the use of constraint equations of coordinates. In the first approach, the original kinematic equations of coordinates in the six-dimensional space (two coordinates describing the position of the output link and four coordinates – the rotation angles...
