| titleOfInvention | Acousto-emission method of determination of frost resistance of materials |
| abstract | The invention is intended to evaluate building materials. Using non-destructive methods for determining the tensile strength P, it was possible to prove that the relative decrease in R during a cyclic change in the external load from zero and during thermal cycling with freezing is the same if the external load is increased to a value P corresponding to the occurrence of continuous acoustic emission (AE) during the first loading after freezing . In this case, due to damage to the material, the load P decreases, during which continuous AE appears during cyclic loading. The relative decrease in P coincides with the relative decrease in R. With this in mind, it is advisable to freeze, heat, material warp, gradually deform with an external load until continuous AE appears, determine the corresponding load value P to this value, cyclically load the material from zero, register P in each cycle, and about frost resistance material is judged by the number of cycles at which (PP) / P is equal to the permissible relative decrease R. Loading the previously frozen part of the surface m Therians indenter is possible to determine the remaining service life of frost without cutting samples, e.g., from the dam body. The proposed method reduces the duration of the test by hundreds of times. 1 ill. |
