The paper proposes a method of direct laser micro- and nanostructuring based on nanosecond lasers with radiation of UV and VUV range. The method allows surface laser treatment of materials with different ph

Thomas Friedrich,Gerhard Schweppenhäuserocessing method that is widely used to form sheet metal parts such as the aviation industry, shipbuilding, automotive and so on. During the sheet metal bending process, the spring-back and forming force are very important output parameters that need to be determined to ensure the accuracy and load c
