Experimental and Numerical Modal Analysis of the Glass Composite Plate Damaged by Cut

The given paper is closely connected with the experimental and numerical modal analysis of glass composite plate damaged by cut. In relation to tested composite, was performed help special measuring device Pulse 12. mentioned supplied company Brüel&Kjearand measurements were carried out using undamaged sample which prepared from material hereinbefore. investigated analyzed plates made six layers glassfibres they arranged under angle 90º (it like fabric off glassfibres). in way joined epoxide resin MGS 285. measurement natural frequencies proportions 78 mm x while ten for each one specified site sample. sample, there wascut length 20 centre border. finite element method software system ADINA v.8.6.2 used frequencies.
