Abstract

A new approach to strength testing of new typical products for our company, called Products' virtual testing, is provided in this work. This approach provides modeling of the construction's nonlinear deformation processes in time, which allows not only to perform calculations of the construction's separate parts but also to perform an analysis of the whole construction's testing. The advantages of a new approach are compared to the classical methods of construction strength assessment. This approach is concluded to be promising and needing to be implemented in the product cycle of the company.
