- Abstract
The research work is devoted to the development of the estimation for dynamic behaviour of external pressure impulse loaded, longitudinally compressed and irregularly heated multiply shell-type composite material made constructions. Last years a great attention is given to composite material made constructions then new machinery is creating. Investigating such constructions serviceability under complex loading conditions is an actual problem in flying vehicle design. Such problem as dynamic behaviour of external pressure impulse loaded, longitudinally compressed and irregularly heated multiply shell-type composite material made constructions is formulated. Thermoelasticity equations for composite material made multiply shells are derived. Differential equations for behaviour of complexly dynamic loaded and heated shell-type composite material made construction are solved. Numerical solution of differential equation for dynamic behaviour of composite material made shells under above-mentioned loading is given. Analytical dependence of critical external pressure impulse for longitudinally compressed and irregularly heated multiply shell-type composite material made construction is derived. Numerical solution of the equation allows evaluating consistency of hypothesis about unbiased sampling for dimensionless deflection of external pressure impulse loaded, longitudinally compressed and irregularly heated composite shell. The results allow evaluating load-carrying of the composite shell-type constructions at the conceptual design stage.
