Issue: №6 2018

In dynamic process the behavior of construction depends on their surface of fluidity. In article analytical decisions for a rigid plasticity system with two degrees of freedom in case of dynamic problem definition when external influence has impulsive character (initial
speed of a system is set) are received and analysed. The mathematical model of a rigid plasticity system dynamic behavior at account and not accounting of interaction projections of plastic reactions effect are provided in article. The interrelation between these approaches is found. An assessment of construction operability is given and also limit cases of the received decision are considered. Comparison with the simplified problem definition upon transition from elliptic to rectangular curve fluidity is carried separately out.
