This thesis is devoted to the numerical solution of dynamic problems involving thin-walled structures.
Special consideration is paid to the effects of contact-impacts.
Thus, the main effort is concentrated on studies, development and computer program implementations of efficient algorithms for analysis of dynamically loaded shell structures, including contact-impacts and severe structural deformation. Recent developments in the formulation of efficient finite elements for dynamically loaded shell structures are studied. The efficiency and the behaviour of this element type are compared with existing shell and solid elements implemented in the same program system. Hourglass resisting algorithms are reviewed and formulated, and parameter studies are carried out. A new contact interface algorithm for dynamic analysis with explicit integration is presented.
