Experiment: Mechanical Testing- Impact & Hardness Testing
The main objective of this experiment is to introduce two important basic mechanical property tests; hardness (using Rockwell testing) and impact (using Charpy testing). Chauvenet’s Criterion will be applied to identify outliers and probability paper will be used to ascertain whether or not the repeated measure hardness data is normally ...

A fundamental study on the flow past a circular cylinder ...
imechanica.orgFlow patterns generated around a circular cylinder immersed in a uniform flow are shown in Figure 1 (Hughes & Brighton, 1999). In relation to the flow around an object, a combination of a uniform flow with a circular cylinder will be the simplest case. The pattern of this flow varies depending upon the Reynolds number.

plastics-rubber.basf.comThe hardness of elastomers such as Elastollan® is measured in Shore A and Shore D according to DIN ISO 7619-1 (3s). Shore hardness is a measure of the resistance of a material to the penetration of a needle under a defined spring force. It is determined as a number from 0 to 100 on the scales A or D. The higher the number, the higher the hardness.
