Hi
Has anyone met the problem that if adding the I/O (just reading
externals or writing externals) in UMAT, the computing speed becomes quite
slow, but the CPU occupied by the ‘standard’ process is few, sometimes even keeps zero all
the time. The I/O is quite simple, just using the 'OPEN' , 'READ' and 'WRITE'.
That would be great if anyone knows the reason for this problem.
Thanks and Regards

Hi there,
Can anyone explain me the results I got from Explicit? I am investigating cracks propagation in hybrid timber-glass beam. It is a I-shaped section and consists of timber flanges and glass web bonded with an adhesive.
Please look at the attached diagram - Force versus vertical deformation. Until an initial crack it is almost perfectly linear. But what happens after the glass failure? What could be the reason that the force changes like a wave?
