Hello I am a student of the University of Manchester. I am modelling a SHPB assembly together with the specimen, and I am having trouble with placing the loads,creating the boundary constrain between the incident, transmitter bar and the specimen. I created the interaction between the assembly with a suppressed TIE, and after loading and submitting the job I kept on getting errors. The load did not transmit to up to a quarter of the incident bar.
I neeed suggestions on how to apply the attachment between the separate components that make up the assembly, how to time step properly and the loading sequence.
I made use of ABAQUS Explicit
Thanks
