This article focuses on the formulation of some scalar factors which are uniquely expressed in terms matter variables for dynamical charged dissipative cylindrical geometry a standard gravity model $$\mathcal {R}+\Phi \mathcal {Q}$$ ( $$\Phi $$ is coupling parameter, {Q}=\mathcal {R}_{\varphi \vartheta }\mathcal {T}^{\varphi }$$ ) and calculates four scalars by orthogonally decomposing Riemann ...

Abstract A new type of ceramic armor structure is designed by using spherical cylindrical splice plate as panel with metal steel frame applied, TC4 titanium alloy and 685 back respectively in this paper. Ballistic test was carried out firing 14.5mm penetrator projectile ballistic gun. Results show that: damage area smaller when the weight lighter aftereffect similar, performance better than tha...

We use fully-resolved simulations to predict the force and torque acting on a long cylinder or fiber inclined with respect incoming flow. Results obtained in viscous regime are compared predictions of slender-body theory, possibly incorporating finite-inertia corrections. Numerical results used build approximate models for valid from creeping-flow conditions up upper limit stationary inertial r...

The main focus of this paper lies in the drastic model reduction for a complex multi-scale problem linear elasticity. core work structural optimization periodic perforated cylindrical shells under given load on small portion surface. Periodic structure shell is frame beams. Algorithm presented utilizes two our recent analysis works homogenization and dimension 3D to two-dimensional homogenized ...
