huge difference of Young's modulus in sandwich structure
800x600
Hello,
I am modeling a plate under three point bending with Abaqus. The plate
is a sandwich structure with aluminum plate (thickness: 5mm), adhesive glue (thickness:
0.02mm) and a kind of foam (thickness: 15mm) bonding together. Their Young’s
modulus is at the order of 100GPa, 1MPa and 100MPa. While in incremental
calculation, the job is always be aborted for not achieving convergence. I just
wonder whether the cause of not achieving convergence should be attributed to
the huge difference in Young’s modulus.
Does anyone know how to solve this problem?
Thanks in advance.
