Test Case

A cylindrical rod assembly of four cylinders connected end to end has frictionless support applied on all the cylindrical surfaces and both the flat end faces are fixed. Other thermal and structural loads are as shown below.

Find the Deformation in the x direction of the contact surface on which the remote force is applied. To get accurate results apply a global element size of 1.5 m.

Material Properties

Geometric Properties

E = 2 x 10¹¹ Pa

ν = 0

α = 1.2 x 10^-5/°C

Diameter = 2 m

Lengths of cylinders in order from End A: 2 m, 5 m, 10 m, and 3 m.

Given temperature (End A) = 1000°C

Given temperature (End B) = 0°C

Remote force = 1 x 10¹⁰ N applied on the contact surface at a distance 7 m from end A.

Location of remote force = (7,0,0) m
