Giving up the hypothesis of σ_(γγ)= e_(γγ)= e_(αγ)= e_(βγ)=0, which is the well- known hypothesis of indeformable normal of shell surface as usually adopted by the current shell theories, this paper presents a new theory on thermal stresses in shells. Considering the effects of stress σ_(γγ), the stress normal to shell surface due to temperature, some basic relations were derived here for arbitrary shape of shcll. Theyare (1) thermal elastic relations. where and θ_o and θ_i are the temperature increment at ...
Certain difficulty arises when it is necessary to analyze elastic stability of thin-walled curved open tubes subjected to concentrated forces and moments and constrained by rather complicated boundary conditions. In this paper, starting with the equilibrium equations of curved open tube and using the method of fictitious distributing loading, we have obtained a system of ordinary differential equations with variable coefficients which can be used to calculate critical loads of structures. ...
This paper gives a simplified calculation method which solves equilibruim compositions of the combustion products of composite propellants (including C.H.O.N.Cl.S Al. Cu.
