摘要：

This　paper　deals　with　an　inverse　problem　based　on　the　simultaneous　use　of　the　Finite　Element　Method　(FEM)　and　the　experimental　method　for　the　shape　reconstruction　of　defects　in　inhomogeneous　material.　In　a　cylindrical　specimen　including　different　defects,　a　classic　2D　finite　element　method　is　used　for　flaw　echo　computations.　Results　obtained　from　such　calculations　are　used　as　the　data　for　the　inverse　problem　solution.　A　brief　result　of　the　shape　reconstruction　of　the　experimental　method　is　also　presented.　Although　two　different　ways　get　the　same　results,　revealing　drawbacks　and　advantages　of　the　proposed　approach　as　regards　to　the　results.
