Level-Sets and Arlequin framework for dynamic contact problems

It is expected that the difference between a classical model and crystal plasticity can be still larger if two rough surfaces are considered instead, since the way

The methodology is illustrated on the line following problem of a sailboat and then validated on an actual experiment where an actual sailboat robot, named Vaimos, sails

Therefore, the level set based numerical algorithm can perform topology optimization either if the number of holes in the initial structure is sufficiently large [14,17,20] or if

The penalty method is a classical and widespread method for the numerical treatment of con- strained problems, in particular the unilateral contact problems arising in mechanics of

In figure 5, we show the time history of the displacement, velocity and contact pression of the bottom contacting point of the cylinder obtained by both of a dissipative Newmark

Among other approaches, let us mention the Partition of Unity Method [8] and the Extended Finite Element Method (X-FEM) (e.g. These methods, quite reminescent to Treftz approach,

But to our best knowledge and due to the aforementioned intrinsic difficulties of the impact problems (strong nonlinearities and both space and time irregularities and

• In this section, we proved conservation energy of the discretized contact elastodynamic problem using an appropriate scheme and a choice of con- tact condition in terms of
