Floating point exception (core dumped)
any idea what that means

[Prof. S. Govindjee]

The back trace does tells you that you are looking for some type of floating point error, maybe a division by zero.  Have a look at line 977 in elmt02.f and in the routine bondedfibre.  I would suggest running in a debugger like gdb and putting a breakpoint in elmt02.f at 977 so that you can interrogate the contents of the variables just before the the Floating point exception occurs.
