Analysis Type(s): Nonlinear Transient Dynamic Analysis (ANTYPE = 4) Element Type(s): Spring-Damper Elements (COMBIN14) Combination Elements (COMBIN40) Input Listing: vm9.dat Test Case A two-spring system is subjected to a force F as shown below. Determine the strain energy of the system and the displacements δx and δy.

Combination elements (COMBIN40) are used to provide damping in the X and Y directions. Approximate damping coefficients cx and cy, in the x and y directions respectively, are determined from ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . ©...
