The finite Element Method was used to validate the procedure used by Chen to determine DSIF in a centrally cracked plate loaded with a step function. Once the validation is done, length and orientation of the crack are varied to determine their effect on wave propagation and DSIF values. To expand the study, the analysis is also applied to cracked tubular elements. In all cases, DSIF variation is interpreted as a function of the stresses produced by the interaction of the elastic waves with the boundaries of the structural element studied. Dependence of DSIF values on dilatational, transversal and Rayleigh waves is seen. These elastic waves and their interaction with the structural element boundaries and crack surfaces determine load and unload cycles at the crack tip affecting the stress field and DSIF values. 2006 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57065002 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
