is a

indicative
of a material’s ability to

Atomic vibrations
3 Types of Thermal Expansion
- Linear expansion
- Area expansion
- Volume expansion
is the phenomenon by which heat is transported
from high- to low-temperature regions of a substance.
Thermal conduction
are stresses induced in a body as a result of
changes in temperature. An understanding of the origins and
nature of thermal stresses is important because these stresses
can lead to fracture or undesirable plastic deformation.
Thermal stresses
- Most solid materials expand upon heating and contract when
cooled.
THERMAL EXPANSION
The capacity of a material to withstand failure (Crack formation and brittle
fracture) is termed its thermal shock resistance.
