- | In this commit, a new contact traction element was created to set the traction force to zero at the nodes that are in contact within a specified contact interaction. | + | ===== Description ===== |
+ | In this commit, the out-of-plane thickness evolution in the generalized plane strain state is coherently accounted for in the computation. | ||

+ | The test case in the following figure is identical to what was decribed previously. | ||
+ | The gap can be computed in various ways, numerically, | ||
+ | * First, the numerical computation simply consists in extracting the gaps in the Metafor computation and choosing the one at $P_{4}$. | ||
+ | * Second, the analytical computation provides the value of the gap via the following formula: $\text{gap} = p/k_{n}$, where $k_{n}$ is the normal penalty coefficient. | ||
