As we discussed in this chapter, when selecting materials for mechanical applications, the value of the modulus of resilience for a material shows how good the material is at absorbing mechanical energy without sustaining any permanent damage. Another important characteristic of a material is its ability to handle overloading before it fractures. The value of modulus of toughness provides such information. Look up the values of modulus of resilience and modulus of toughness for (a) titanium and (b) steel.
What will be an ideal response?
(a) Titanium: Modulus of Resilience: 3390 KJ/m^3 (e.g., Grade 6); fracture toughness: 28 to 108 MPa.m^1/2(for most Titanium Alloys)
(b) A36 Steel: Modulus of Resilience: 0.13 ksi; modulus of toughness: 17.9 ksi
