Program CGP-TROl was developed to investigate two-dimensional models for the initiation and growth of the I-mode crack in notched beams in bending. It is based on the fictitious crack model (FCM) and the finite element method is employed for analyzing. The text presents fundamental concepts and the formulation of the program. Simultaneously some new for~ulae for calculating numerically the stress intensity factor are developed. These formulae may be used in case there are no singular elements close to crack tip as long as these elements are small enough. The procedures for calculating the elastic displacements and stresses by the finite element method have been presented in many books that are not necessary to be described in the text. The examples are presented in the text including the example for checking the program by the data presented in references (the program FEMALES used by Roelfstra and Wittmann) and the example describing the crack growth of a concrete beam in three-point bending with different notched depth.
