Hello Youngjin,

You could also use *MAT_GLASS (*MAT_280) to model your laminated glass. You will find more information here:

Here is an example:

You will find more information on *MAT_280 in the user manual volume  II and here:

Another approach would be to use peri-dynamics:

You can search for  "peridynamics" on dynalook.com for more papers.

Let me know how it goes.
