Abstrakt
The book contains results of numerical calculation and their comparison with
experimental tests carried out on the specimens CT. Crack propagate until damage
specimen was achieved. The angle between the direction of crack propagation and the
direction of the artificial crack was measured.
Author during numerical investigations compare Burzynski and Huber-MisesHencky
hypothesis. The Burzynski hypothesis gives very good results for brittle
materials which has different properties for tensile and compression it means that
relationship between limit stress for compression Re to limit stress for tension Rm is
greater than 1 (for example: epoxy resign, cast iron).
Influence of relation R.!Rm on angle of crack propagation was carried out. The
results of investigation gives information that for relation R.!Rm greater than 1,3 the
value of angle of crack propagation is constant, and its value is about 76°.
The experimental investigation is solved by photoelastic method. The numerical
results were obtained using finite element method package ANSYS. The problem is
solved by "element birth and death" method.
Results of investigations of cracking of reinforced specimens are presented.
