Brittle failure in Abaqus

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?

Brittle cracking in brittle materials

Hi there,

 I am trying to simulate a crack opening process in ABAQUS. I start up from a simple model of plate with a notch subjected to tension. I would like to see the crack opening. To model a brittle mnaterial behaviour I have added a brittle cracking with sub-option brttle failure and brittle shear.

Please look at dat file:

*Heading

  *Node

  *Element, type=CPS3

  *Element, type=CPS4R

  *Nset, nset=ASSEMBLY_PART-1-1__PICKEDSET2

  *Elset, elset=ASSEMBLY_PART-1-1__I1
