HI all,
I am trying to simulate bolted lap joints by using adhesive bonded aluminum laminates and gave interaction properties and all. When I am runing the input file howerver, I get errors of:
CONVERGENCE CHECKS FOR EQUILIBRIUM ITERATION 1
AVERAGE FORCE 6.692E-04 TIME AVG. FORCE 6.692E-04
LARGEST RESIDUAL FORCE -3.936E-02 AT NODE 1449 DOF 3
INSTANCE: RIVET-3
LARGEST INCREMENT OF DISP. 6.190E-02 AT NODE 272 DOF 3
INSTANCE: RIVET-2
LARGEST CORRECTION TO DISP. 6.178E-02 AT NODE 272 DOF 3
INSTANCE: RIVET 2
FORCE EQUILIBRIUM NOT ACHIEVED WITHIN TOLERANCE.
***ERROR: TOO MANY INCREMENTS NEEDED TO COMPLETE THE STEP
I have also tried by reducing the increments which gives me different error like
** ERROR TIME INCREMENT REQUIRED IS LESS THAN THE MINIMUM SPECIFIED
Any ideas or suggestion will help me a lot guys
Ive attached my input file.
Thanks a lot
