Abstract
Experiments were carried out on the dependence of strain on stress in the test for a flat straight bend of samples of non-irradiated and irradiated corrugated Plexiglas. It is found that with increasing voltage the relative elongation of corrugated samples of Plexiglas (both non-irradiated and irradiated) increases linearly. It is revealed that the irradiation leads to a noticeable change in the deformation-strength characteristics of the material, manifested in a decrease in plasticity. Elongation striped acrylic plastic after irradiation is changed to 20 %, and the pyramid – 40 %. In this case, the strength change does not occur. The obtained curves of lgt versus Ơ are satisfactorily described in the framework of the linear model.
