Диагностика остаточных напряжений в биметаллических пластинах алюминий-сталь с использованием лазерного ультразвука и зондирующего отверстия

The character of changes in laser photoacoustic signals near small-diameter holes in layers of aluminum and steel in a bimetallic plate obtained by hot rolling is investigated. The experimental results are compared with the solution of the classical Kirsch problem for stress distribution around a ci... View More
