| The nonlinear model interwire contact problem has been solved by the method of matched asymptotic expansions. |
|
| However, this problem has not been studied to date due to the lack of a scheme effectively determining the interwire contact status. |
|
| The interwire contact interaction is treated as a frictionless unilateral plain strain problem. |
|
| The magnetostatic interactions between neighboring Co nanowires might also play an important role, since the interwire distance is far smaller compared to the diameter of the Co nanowires. |
|
| Consequently, several finite element parameters, such as the load ramp profile and duration, effects of damping and interwire friction, become critical for an accurate and efficient model. |
|
| In order to express the interwire contact deformation in terms of the parameters describing the strand deformation, we formulate a two-dimensional model interwire contact problem. |
|
| And it is found that the interwire contact status of the strand may change with the varying loads, resulting in the unstable distributions of the interwire contact pressure and deformation. |
|
| We introduce explicit many-body interwire interactions that preserve time reversal symmetry and give energy gaps to all low energy degrees of freedom. |
