A LVDT with a resolution of ±1 μn mounted on the vertical slide was used to measure the angle of inclination of EN8 flat. The pins were made of an AI-3.5%Mg alloy with a total sắt, Mn, and Si content of about 1wt.%. The pins were 10mm long, 3mm in diameter with a tip radius of 1.5mm. The pins were first machined, and then were electro-polished to remove any work-hardened layer that might have formed during machining. Have carried out transverse impact tests of single strap joints by a drop weight testing machine.
According to this latest study, the 2021 growth of Visual Field Testing Equipment will have significant change from previous year. By the most conservative estimates of global Visual Field Testing Equipment market size will be a year-over-year revenue growth rate of % in 2021, from US$ million in 2020. Over the next five years the Visual Field Testing Equipment market will register a % CAGR in terms of revenue, the global market size will reach US$ million by 2026. The United States Ceramics and Glass Testing Equipment market is expected at value of USD million in 2021 and grow at Impressive CAGR during review period.
Even for small test series starting with approximately 10 specimens, an automated tensile testing system proves worthwhile. With the use of a simple robotic testing system for tensile tests, qualified laboratory personnel are relieved of routine responsibilities and therefore available for more complex tasks. The moving crosshead is essentially a cross beam that is controlled to move up or down. For a tensile test, the crosshead speed of the testing machine is directly related to the strain rate in a test specimen. The universal testing machine can be re-configured and physically converted for a flexure test.
As the applications of universal material testing machines are too extensive, we can’t list them all here. Please check the UTM machine’s frequently done test items listed below. If you want to know more about the application, please liên hệ us directly.
The CE-compliant electrically interlocked safety device prevents interference with the machine during the test. Test software provides fully customized parameter definition, test method development tools, automatic test control, data collection, results analysis, and reporting. Different types of extensometers with accuracy of up to ±0.1 % of the indicated value are available depending on requirements. Extensometers separate to grips or platens can directly measure deformation of specimens. The machine is supplied complete with high precision load cell.
For a typical compression test, the machine is set up with the appropriate compression fixtures for the type of material to be tested. The corresponding test parameters are then configured, and the specimen is placed between two compression platens until a specified load or distance has been reached, or until the specimen breaks. Common measurements include the elastic limit, the proportionality limit, the yield point, and the compressive strength.
The area above the loading platform is for compression tests on a wide range of materials such as wood, brick and mortar. A tensile testing machine that has a simple structure ans is capable of carrying out strength measurement of a sample with very small tensile strength is provided. “What are a universal testing machines” and “what can I use universal testing machines for” are some of the questions we answer in the text below. Different models of Universal Testing Machines have different load capacities, some as low as 2 kN and others as high as 3,000 kN. In addition, an electronic universal testing machine will have built-in programming, features and functionality that allow the user to control certain test conditions and adjust key parameters lượt thích the test tốc độ and cycle time.

Since the conviction, Holmes and Theranos have been the focus of a Hulu limited series, “The Dropout,” based on the ABC News podcast of the same name. Besides the criminal case, Holmes was also involved in a number of civil lawsuits, including one in Arizona brought by former Theranos patients over inaccurate blood tests. The lawyers representing her in the Arizona case said in late 2019 they hadn’t been paid over a year and asked to be removed from Holmes’ legal team.
