Description
Изобретение относитс к исследовани м механических характеристик листовых материалов нутом сжати рабочей среды в замкнутом объеме.The invention relates to the study of the mechanical characteristics of sheet materials by chipping the working medium in a closed volume.
Известен способ испытани листовых материалов при двухосном раст жении, заключающийс в том, что испытуемый образец прижимают к матрице, нагружают и определ ют деформацию образца, наклеива на него тензодатчики.A known method of testing sheet materials under biaxial stretching is that the test sample is pressed against the matrix, the strain and the deformation of the sample are determined by gluing strain gauges onto it.
Недостатками известного способа вл етс уменьшение точности замера деформаций при приложении к образцу максимальной нагрузки и ограниченна возможность используемых средств измерени .The disadvantages of this method are the reduction in the accuracy of measuring the deformations when a maximum load is applied to the sample and the limited ability of the measuring means used.
С целью повышени точности измерени деформации в момент действи максимальной нагрузки по предлагаемому способу используют две противолежащие матрицы и одновременно нагружают два идентичных образца от одного нагружающего устройства. Кроме того, с целью упрощени измерений, между каждым образцом и соответствующей матрицей размещают плаетину из высокопластичного материала, например из алюмини , по профилю которой после сн ти нагрузки суд т о деформации испытуемого образца .In order to increase the accuracy of strain measurement at the time of maximum load, the proposed method uses two opposite matrices and simultaneously loads two identical specimens from a single loading device. In addition, in order to simplify the measurements, a placenta of highly plastic material, such as aluminum, is placed between each sample and the corresponding matrix, for example, aluminum is deformed on the profile of the specimen after de-loading.
На чертеже схематически изображено устройство дл реализации предлагаемого способа .The drawing schematically shows a device for implementing the proposed method.
Образцы 1, расположенные на пластинах 2 из высокопластичного материала, например из алюмини , креп тс совместно с плас тинами к противолел ащим матрицам 3 прижимными кольцами 4 с герметизирующими кольцами 5 и через отверстие 6 подвергаютс нагружению от одного нагружающего устройства . После сн ти иагрузки по профилю уцелевшей от разрушени иластины определ ют деформации образцов в любых точках.Samples 1, located on plates 2 of highly plastic material, for example aluminum, are attached together with the plates to the opposing matrices 3 with clamping rings 4 with sealing rings 5 and through the opening 6 are subjected to loading from a single loading device. After removal of the load, the deformations of the specimens at any points are determined from the profile of the survivable Ilastine.
