Kulikov G.M., Plotnikova S.V.On the Use of 6-Parameter Multilayered Shell Models in Structural Mechanics // Scientific article. Journal "Transactions of the TSTU", vol. 10 , Tambov. TSTU publisher house , 2004. (pdf-file) Abstract: The new geometrically exact multilayered shell models are considered.
These models are based on the objective strain-displacement relationships represented in the local curvilinear coordinates and, therefore, may be used for the formulation of effective curved multilayered shell elements. However, the practical use of such elements require the development of constitutive equations, in order to overcome Poisson thickness and volumetric locking phenomena. For this purpose three types of the material stiffness matrix are studied.
Plotnikov P.V., Shurshalov L.V.A Hail from Space: More Dangerous than an Asteroid // Scientific article. Journal "Transactions of the TSTU", vol. 10 , Tambov. TSTU publisher house , 2004. (pdf-file) Abstract: A new problem on the collision of a large space cloud of small dust
particles and a planet atmosphere is considered. The cloud approaches the planet and enters its atmosphere at a very high velocity and has a high, for space conditions, concentration of the particles. Some possible catastrophic consequencies of such a collision are discussed.
