| Popis: | Construction compositions having nonlinear response to dynamic loading are compound compositions possessing disperse and liquid phases. They functionally comprise agents which give the composition the required properties depending on its aim and field of application. Under dynamic loadings such compositions are nonlinearly changed. Though such compositions are quite simple it is necessary to solve a number of tasks when developing their formula. The article considers scientific approaches to design of compound compositions aimed for operation under dynamic loadings. A composition model is proposed and analyzed. Basing on the analysis the formula parameters of the considered compositions are specified. The requirements to disperse and liquid phases are determined. The authors showed that the cancellation of the dependencies of quantity and strength on contacts from the diameter of disperse phase particles influences the strength of the considered compositions. It is noted that spot contact is formed when the layers of liquid phase which surround the contacting particles of the disperse phase merge. The features of the components are specified. The considered features should be preferred when choosing the disperse and liquid phases of compound compositions. |
