Abstract (2. Language):
n this paper we study the effect of change angle the
template in tests of composite materials on the value of
modulus of elasticity. Used two models of templates the first
acute angles and the second non- acute angles and used two
specimens of a composite material in experiments. Many
strain gauges has been installed on the template models in the
region of maximum stress is expected and the other near the
edges of the template, in testing the equipment’s used were
equipment’s tensile testing of materials. From the results has
been reached that the acute angle to the edge of the template
affect the results of a strain gauges which installed in the
region of maximum stress and which negatively affects the
value of the stress intensity. The results indicated that the
value of modulus of elasticity when the template is a non-sharp angle more accurate than the results obtained when the
sharp angle of the template, the reason is that some of the
stress is lost near the edge of the template. The results
obtained in the models we obviously in ANSYS program were
identical with the results obtained from the models used in the
experiments
