... permanent plastic deformation of the material to be tested. However, elastic deformation must be considered in hardness measurement of elastomers. This chapter discusses the equipment and processes involved in the durometer (Shore) test, the International Rubber Hardness Degree test, and other specialized...

... testing and the durometer test method are the most common, although another type of hardness test for plastics is the Barcol method. A rough comparison of hardness scales for these methods is in Fig. 19 , but it must be understood that any conversions from Fig. 19 are only rough estimates that vary...

... that flooring is generally slip resistant. Polished stone may look pretty—but could be a slip hazard. There are standard tests to check the slip resistance of floors in most countries. An earthquake is a stick-slip event between subsurface rock shelves. Lubrication (with water, etc.) can induce...

... often begins with corrosion resistance. It is not enough merely to consider the design conditions. First, the probable service environment must be characterized, including anticipated excursions or upsets in service conditions. The suitability of various grades can be estimated from laboratory tests...

...) specification on most materials that will tell people the nature of test materials. Of course, if heat treatments have been applied, these need to be stated. For metals and ceramics, hardness numbers should be given. For rubbers and elastomers, durometer scale hardnesses should be given. Method...

... — greater stiffness). Similarly, railroad tracks are made from steel because it would be much harder to roll a train car on wooden tracks (less stiffness — lower elastic modulus). Many modern rolling devices have rubber wheels, and in agreement with this law, rubber hardness (durometer) can control...

... by the standard tensile test may be used for an analysis of bending. For good bend design, the tensile stress at point X is less than the ultimate tensile strength, as shown. If the tensile stress approaches or exceeds the ultimate strength, the metal will likely tear or fracture during bending. Fig. 12...
