The results of experimental tests of the bearing capacity and failure processes of models of pre-longitudinal compressed cylindrical shells depending on the magnitude of the force load, energy and distance of the point thermal and electrothermodynamic load from the shell surface were obtained. Experimental studies of the destruction of previously statically loaded cylindrical shell models with the accumulation of damage in the form of an increase in the hole and the accumulation of randomly located cuts-cracks on its side surface were conducted. Finite element modeling was performed and results were obtained of the processes of high-speed penetration of bullet-shaped weapons into a material that simulates the properties of biological tissues. A methodology for applying artificial intelligence elements (machine learning algorithms) has been developed to analyze experimental data from studies of the processes of loss of stability of thin-walled shell structures during the accumulation of damage in the form of holes and cracks of various numbers, sizes, and locations under various types of static loading. The results are presented in the form of fracture patterns and dependences of the magnitude of critical loads on the parameters of damage accumulation. Product Description popup.authors Alla Y.
