It is bout two-dimensionl test in sttics in which one models to it not linerity of contct due to refermeture prtil of the crck. The behvior of the structure is thermoelstic liner isotropic. The cse test understnds two modelings D plne for which one studies the influence of the mechnicl lod fctor. In the first modeling contct with mteril infinimement rigid is used to represent refermeture (symmetricl) crck while in the second boundry condition of type unilterl connection is put in work. rning : The trnsltion process used on this website is "Mchine Trnsltion".
