METHOD OF DETERMINATION OF PRODUCT RESIDUAL LIFE Russian patent published in 2009 - IPC G01N3/32 

FIELD: physics, trials.

SUBSTANCE: invention concerns field of mechanical trials of constructional materials, to be exact to methods of definition of time before fracture. In an expedient samples and a product periodically smoothly unload, fix time or number of the turned out cycles, register an acoustic emission before the relief termination. In the presence of such issue, determine peak value of nondestructive load for the product, and in the absence of an acoustic emission, the residual life of the product is estimated on the net operating time of the product.

EFFECT: determination of time before fracture of a product from a plastic material after an operating time of the guaranteed resource, and also possibility reception to use a resource of devices of a construction without hazard of its failure.
