1.2. Material properties#
Plate for pulley and rope:
Poisson’s ratio: \(0.4762\)
Young’s module: \(147.619{10}^{5}N\mathrm{/}{m}^{2}\)
Finite contact elements:
Integration: Nodes
Method parameter:
coef_regu_cont=1.
1.3. Boundary conditions and loads#
The pulley is stuck:
on its internal surface the displacement is zero in both directions \(x\) and \(y\).
No boundary conditions are imposed on the rope except that of contact.
Charging:
two vertical movements are imposed on both ends of the \(u\mathrm{=}1\) rope
