Abstract We carried out uniaxial compression tests on brittle red sandstone with different heights. The test results show that the uniaxial compressive strength of rock sample increases first and then tends to be stable with the increase of the size. which is approximately stable between 75 and 81 MPa. Both elastic energy and dissipated energy increase with the increase of rock sample... https://www.nacrack.com/great-pick-Refurbished-Sawgrass-Virtuoso-SG500-Complete-Sublijet-Sublimation-Printer-Kit-flash-buy/
