      Hi

      I have modeled two pipes and zero length elastic spring was used at the connection joint. Could anyone please help me telling how I can get shear force and bending moment at the connection joint as below. For shear force and bending moment of this connection which option in LSDyna to be requested in the code.

      It's unclear what type of spring is used and how that spring is attached to the pipes. Your figure makes me think the pipes are modeled with shells. Maybe that's not the case. But anyway, you can get forces and moments at a cross-section using *DATABASE_CROSS_SECTION_PLANE (defines location of cross-section) and *DATABASE_SECFORC (defines time interval for output of cross-section data to secforc).
