What is plastic memory?
If certain plastics (take for instance PTFE) is subjected to stresses below its yield point then it may be subjected to permanent deformation. This deformation will induce certain strains through out the material. If the plastic is heated up, these strains tend to relax which allows the plastic to return to its original shape. This is often refered to as "plastic memory".
What is anelastic deformation?
Anelastic deformation. Deformation processes where a material assumes its original shape after the load is removed, but with a time delay.
How do you calculate permanent deformation?
Deformation is calculated by using deflecto meter.
What is a deformation and what causes it?
Deformation is a change in the shape and volume of a rock, deformation is produced when a rock experiences a stress that is greater than the strength of the rock.
What happens to the chemical reaction when it gets heated?
It may speed up when heated.
What process occurs when glacial ice is heated to 5 degrees Celsius?
deformation
What are causing the sounds from barbecue hotplates when they are first heated or when they cool down?
When the barbique hot plates are heated or coolede down, due to the change in temperature there will be a minor deformation of the material. During this small deformation, the sounds occur.
What two metals make up a bimetal?
Brass and Iron
What will happen to a closed tin container when heated?
1. Deformation 2. Melting 3. Possible "explosion", depending on the content

What kind of deformation leads to deformation?
elastic deformation
Who invented the bimetal thermometer?
John Harrison
What are the types of rock deformation?
elastic deformation, ductile deformation and fracture
What is the bimetal mechanical thermometer?
The bimetal mechanical thermometer uses one end of a bimetallic coil connected to the housing of the device and the other end drives an indicating needle. The bimetal mechanical thermometer is often used in things like refrigerators, air conditioners and heat control.
What is elastic deformation?
Elastic deformation is recoverable deformation. As such, when the load that caused the deformation is removed the material will return to it's original shape.
What happens to wood when heated up?
it will take long to be heated up,
Which is not a form of rock deformation?
ductile deformation
