Solenoid under current load

This is an example of the solenoid under current load simulation, performed with QuickField software.

Problem Type:
Axisymmetric problem of magneto-structural coupling.

Geometry:
Solenoid under current load Calculate the mechanical stress distribution in the solenoid coil carrying current Winding R1 R2

Given:
Inner radius R1 = 5 mm;
Outer radius R2 = 10 mm;
Current density j = 4·106 A/m2;
Coil Young modulus E = 1.075·1011 N/m2;
Coil Poisson ratio ν = 0.33.

Problem:
Calculate the mechanical stress distribution.

Result:

Von Mises stress distribution in solenoid under current load:
