A marked article includes a substrate including a first surface and a surface material, a raised pad on the first surface, the raised pad including a second surface, and a design on the raised pad. The raised pad is formed on the first surface using a material addition process to prevent mechanical stress from being propagated from the raised pad to the substrate in response to the design being formed on the raised pad.

Material addition for article identification

A method for marking an article may comprise forming a raised pad on a substrate of the existing article by applying a material to a surface of the substrate using a material addition process, and forming a design on a surface of the raised pad. The raised pad may be formed on the surface of the substrate to prevent mechanical stress from being propagated from the raised pad to the substrate in response to the design being formed on the raised pad.

A shock strut is disclosed. The shock strut may have multiple pistons and multiple chambers. In this manner, the shock strut may compress different lengths for different applied forces at different points during its stroke.
