-====== S-Rail shaped deep drawing ======
+====== Elastoplastic Ring Collision ======
+  * **Solver**: LAMMPS with the USER-SMD package
+  * **Method**:
+    * Total Lagrangian SPH to eliminate the tensile instability
+    * Anti-hourglass control to reduce zero-energy modes
+  * **Material**:
+    * Ring on the left: elastic
+    * Ring on the right: elastic perfectly plastic
+  * **Interaction**: repulsive Hertzian force
+  * **Post-processing**: ParaView
-  * Deep drawing of an "S-shaped" rail.
-  * The die and the punch are rigid.
-  * Friction is taken into account between the tools and the blank.
-  * Springback is computed removing the tools and using an implicit scheme.
