- Abstract
- A numerical and analytical model of short-term creep of a metal-composite multidirectionally reinforced with wires has been developed. Calculations of short-term creep of flat metal-composite samples were carried out when a generalized plane stress state was implemented in them. It is shown that, due to the significant physical nonlinearity of the problem under consideration, a change in the reinforcement structure of a metal-composite operating under conditions of short-term creep has a significantly greater impact on the change in its mechanical response than when operating under conditions of purely elastic deformation. With some (for example, rational) reinforcement structures, the components of the metal-composition can deform in a way that is usually characteristic only of polymers, showing signs of limited creep.
