Experimental study of elastic-plastic deformation of a cylindrical shell made of steel 45

Relevance. The use of shells as thin-walled structures for various industries is very diverse. Spherical are widely used in the aircraft industry, circular cylindrical oil and gas more than 30 analytical forms have been construction industry. All elements shell undoubtedly subject to strength calculations. Also, a separate role study occupied by experimental part, which confirms or refutes calculated equations, this indicates undoubted perspective relevance modeling loading structures. aim assess condition under three-parameter tensile, compression torsion forces. Methods. Experimental studies on deformation carried out laboratory conditions prototypes made steel 45 GOST 1050-2013 presented, sample modeled, similar possible applying loads existing Results. diagrams material planes given, development after joint efforts stretching torsion, well destruction estimated. For conducted experiment, real design has selected, which, when certain created, can experience appropriate loads.
