These formations have been subjected to cyclic loads over time, causing fractures that trend to spread at subcritical stress intensity values. Similarly, it presents the results of testing conducted on nine specimens of the Tambor Formation from 2 different outcrops to establish the testing traceability in the equipment. 2011 artículo científico 0122-5383 https://www.redalyc.org/articulo.oa?id=46522249003 en http://www.redalyc.org/revista.oa?id=465 CT&F Ciencia, Tecnología y Futuro application/pdf ECOPETROL S.A.
