| Abstract | |
Many engineering scenarios involve contact between beam structures or, eventually, self-contact. Specifically when dealing with a beam submitted to large torsion loads and considering large displacements and rotations, it is possible to occur self-contact. Beams with low bending stiffness loaded with large torsion can present a loop, followed by self-contact and sometimes a snarl formation. This work presents a numerical model and numerical procedures to solve such a kind of self-contact in beams under loop formation. Numerical examples are presented in the context of initially straight nitinol beams. Numerical tests showed that friction may influence loop and snarling formation. Numerical models could predict self-contact occurrence events with good agreement with experimental results already published in literature. Snarling patterns (when occurred) were also predicted correctly, but with delay when compared to experiments. This delay showed to be friction-dependent. (AU) | |
