Unformatted text preview: ement = 3.75mm C = 9E8 mm2/s2 K Analysis Assumptions and Modeling Notes
In this test the two blocks are modeled using PLANE13 elements with CONTA171 elements placed on the bottom
surface of the sliding block, and TARGE169 elements placed at the top surface of the fixed block. In the first load
step, the sliding block moves 3.75 mm on the surface of the fixed block with an applied pressure of 10 N/mm2.
The displacement of the sliding block occurs within a time period of 3.75 ms. Heat is generated by friction and
is absorbed by the two blocks. To obtain the steady-state solution, a second load step with 100 time steps was
performed with no loading at a duration of 1s. The calculated steady-state results were taken from the end of
the final load step.
The same analysis is repeated using Pure Lagrange Multipliers method (KEYOPT(2) = 4 -- Pure Lagrange multiplier
on contact normal and tangent) of CONTA171 elements. Results Comparison
