ST7-1.50.40.5 Determining Appropriate Contact Stiffness
Contact is modelled in Strand7 using a special type of beam element. These beam elements react load nonlinearly, and in proportion to axial compression. The stiffness of these contact elements can affect the solution results accuracy and convergence. There are many physical situations that may be modelled with various configurations of contact elements. This Webnote aims to provide a guideline of what the axial stiffness value should be. Refer to ST7-1.57.20.8 Contact Element Fundamental...
