Abstract

Numerical-analytical methods based on variation approach to the tasks of mechanics of deformable solid, liquid, gas, hydro- and thermodynamics, multilinked contact and on analytical decisions of loosely-coupled tasks are presented in this paper. The suggested numerical-analytical method allows investigating on high technological level the high-strength joints with guaranteed interference (pressed, hydropressed, thermal, multilayered, autofrettaged, multi-contact (polyjoints)) at various stages of life cycle, except for recycling. Method allow: to determine mode of deformation, joint loading capacity in view of technology factor influence; to calculate parameters of technological processes with the diverse contact effects proceeding in joints, assembled by various methods.
