Description
Известные способы определени модул сдвига листового ортотропного материала заключаютс в том, что испытуемый образец в форме пр моугольной пластинки подвергают скручиванию с последующим измерением углов закручивани , по которым и рассчитывают модуль сдвига. При этом используют специальные машины, имеющие ограниченное применение, способные создавать крут щий момент от 0,1 до 1,2 кг1см.The known methods for determining the shear modulus of an orthotropic sheet material are that the test sample in the form of a rectangular plate is twisted followed by measuring the twist angles, from which the shear modulus is calculated. At the same time, special machines are used that are of limited use and capable of generating a torque of from 0.1 to 1.2 kg1cm.
Предлагаем;,ш способ позвол ет упростить метод определени модул сдвига, дл чего пластину нагружают четырьм взаимно уравновешенными силами, приложенными в ее углах с последующим измерением прогиба угловых точек.We propose;, the method allows us to simplify the method of determining the shear modulus, for which the plate is loaded with four mutually balanced forces applied at its corners with subsequent measurement of the deflection of the corner points.
На чертеже дана схема нагружени образца описываемым способом.The drawing is a diagram of the loading of the sample by the described method.
Испытанию подвергают стеклопластиковые квадратные пластины со стороной 30 и толщиной 1-2 мм.The test is subjected to fiberglass square plates with a side of 30 and a thickness of 1-2 mm.
Результаты испытани различных образцов представлены в таблице.The results of testing various samples are presented in the table.
