Equation (4.25) of EN 1993-1-2

{Δθ}_{a, t} = k_{sh} \cdot \frac{\frac{A_{m}}{V}}{c_{a} \cdot ρ_{a}} \cdot {\overset{\cdot}{h}}_{net, d} \cdot Δt

k_sh	Correction factor for considering shadowing effect
A_m/V	Section factor (represents the ratio of the exposed surface area to the volume)
c_a	Specific heat capacity
ρ_a	Density of steel
Δt	Interval for the time step
h_net,d	Net heat flux
