Within the framework of the linear theory of elasticity, the analytical equations for the components of the stress tensor for а plane with а circular inclusion under tensile loading have been derived using the method of superposition. The given approach allows one to describe the plane-stress state of the plane both for the case of rigid and "soft" inclusions. The obtained solutions have been c...

In the present work, the free vibration behavior of rectangular graphene sheet under shear in-plane load is studied. Nonlocal elasticity theory has been implemented to study the vibration analysis of orthotropic single-layered graphene sheets (SLGSs) subjected to shear in-plane load. The SLGSs is embedded on a viscoelastic medium which is simulated as a Visco-Pasternak foundation. Using the pri...

Measurements of the roll-damping derivative (lp) of three wing planforms were made by the free-flight roll-balance technique over the Mach number range 0-7 to 1.4. The wings were all of RAE 102 section, 7" 5 per cent t/c and aspect ratio 2.83 but varied in sweep and taper ratio. The two wings of taper ratio 0.33 showed little loss of damping in the transonic region but the 50 deg delta wing suf...
