Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 An analysis of existing methods for strength assessment of the glazing and problems that arise during its operation and manufacture, which lead to decreasing strength and durability. Refined approaches to the assessment of the strength of multilayer elements of structural optics under operational and emergency loads, taking into account the residual stresses in an ion-strengthened glass. The parameters of glazing load at operational and emergency loads are determined. The analysis of the general character and level of tension in glazing layers at operational and emergency loadings, and also typical damages of glazing is carried out. The method of solving the thermoelasticity problems of multilayer shells with a non-canonical form in the plan is developed, which allows to present the problem solution in analytical form. Scope is the aviation industry of Ukraine. Product Description popup.authors popup.nrat_date 2022-03-09 Close
