Study of the crack growth arrest in laminated metal composites

The results of experimental and theoretical investigation of the slowing down of failures in laminated-plated composites are reported. Factors that determine the slowing down of a major crack in the conjugate zone of heterogeneous constituents are pointed out. A possibility is shown of strengthening bodies with cracks or crack-like defects by using plating layers or stiffening ribs. Calculation formulas are suggested for determining the parameters of the strengthening plating layers ensuring a steady growth of cracks as they open up on the composite layer interface boundary
