False
What are the six broad classes of engineering materials?
Metals, polymers, elastomers, ceramics, glasses, and composites
What is a characteristic of metals that allows them to be formed by deformation processes?
Ductility
What is a limitation of metals due to their ductility?
They are prey to fatigue and have poor resistance to corrosion
What is the difference in strength between ceramics in tension and compression?
Brittle fracture strength in tension, and brittle crushing strength in compression, which is about 15 times larger
Why are ductile materials more resistant to stress concentrations?
They can accommodate stress concentrations by deforming, redistributing the load more evenly
What happens to ceramics when they are subjected to stress concentrations?
They have a low tolerance and can fracture
What are the advantages of ceramics in engineering applications?
They are stiff, hard, and abrasion-resistant, retain their strength to high temperatures, and resist corrosion well.
What is a limitation of polymers in engineering applications?
They creep, even at room temperature, and their properties depend on temperature.
What is a key advantage of polymers in design?
They can be easily shaped and moulded into complicated parts with multiple functions.
What is a limitation of composites in engineering applications?
They cannot be used above 250°C because the polymer matrix softens.
Why are ceramics more difficult to design with than metals?
They have a wide scatter in strength and the strength depends on the volume of material under load and the time for which it is applied.
What is a benefit of using polymers in terms of strength-to-weight ratio?
They are as good as metals in terms of strength-per-unit-weight.
