From the results obtained from the experiment, we can see that the specimen fracture differently. The mild steel fracture but did not break completely and some part of the steel still attached therefore it is said to be in a ductile manner. The carbon steel is said to be in a brittle manner although it .
Charpy impact testing (also known as the Charpy v-notch test) is a high strain rate testing standard that determines the amount of energy absorbed by a material during a fault (Kim et al., 2015). Metallic materials
RESULTS AND DISCUSSION The specimens were tested by Charpy impact machine and the results are shown by Fig. 3. As can be seen, adding nano clay could increase the impact performance of PP/EPDM . ies that report Charpy impact test results for cementitious com-posites. Commentary on these topics is provided based on sound mechanical principles in the hopes that this discussion will prove useful in the development of a standardized test method for Charpy impact testing of cementitious composites. The Charpy TestThe Charpy impact test is carried out in a 3-point flexure setup.The Charpy specimen is centered on the supports in the pendulum impact tester and rests against two anvils. In the case of notched specimens, the notch faces away from the pendulum hammer and is placed exactly across from the point at which the hammer strikes the specimen.The Charpy impact test, also known as the Charpy V-notch test, is a high strain-rate test that involves striking a standard notched specimen with a controlled weight pendulum swung from a set height. The impact test helps measure the amount .
Charpy impact testing determines the impact energy of materials. The test procedure, the application of charpy testing, factors affecting impact energy, the ductile to brittle transition are all covered.The overall purpose of this research is to explore the usage of an impact testing machine, specifically the Charpy Impact Test device, to better understand the principles behind impact testing in order to further develop engineering skills in . × . this article aims to study by numerical simulation the two types of steels (35CrMo4, C40) in . Furthermore, the Charpy impact test results are affected by many factors, and scholars have conducted many studies in this area. Madhusudhan and Cao studied the effect of several different striker velocities on the Charpy impact test of 300 maraging steel and X80 pipeline steel using ABAQUS software. In addition, it has important research .
