Question
Plastics are made of long chains of repeat units called. If these materials lack crystalline structure, they are termed and will likely exhibit linear/non-linear elastic behaviour The material property____ is calculated as the area under the elastic portion of the stress strain curve, _____is calculated as the area under the plastic portion of the curve, and is often determined from the failure strain. Based on electrical conductivity, there are three classes of materials:_______, _______, and______.Explanation / Answer
11) polymers , rubbers ( amorphous )
12 ) yield strength , tensile strength , fracture stress
13) conductors, semi-conductors , insulators
