Thermal deformation


A beam consists of one or more layers of different materials. A change in temperature or a heat flow through the beam causes it to bend.



Step 1 Input system size

ΔT [degC] Temperature offset
( from undeformed temperature)
Q [W/m2] Transverse heat flux
L [mm] Length of beam
n Number of layers
