| Beskrivning |
There are offered methods of faults reconstruction in stratified composites - stratifications (the interface flaws). Inverse geometrical problems of reconstruction of flaws are reduced to a solution of sequence of systems of the BIE obtained on the basis of reciprocity theorem of operations at established oscillations of expert samples. Solution BIE will be carried out on the basis of a combination of FEM, a method of BEM and a method of a regularization of A.N.Tihonov. As the additional information for a solution of inverse problems the field of displacement measured on a part of exterior boundary of a skew field, free from mechanical stress. Numerical examples of identification of stratifications and ruptures surveyed within the framework of a flat problem of theory of elasticity.
