Plasticity

Tensile test under LS-DYNA

Submitted by Manaliac on

Dear all,

I would like to run a tensile test under ls-dyna of a mild steel  and
apply a 7000 N load to the dog bone specimen on a explicite scheme.

Unfortunately, I
have wild deformations ( and an error) on the nodes on edges where the
load is applied, so can you please tell me what are the importants
constants (like time termination, mass scale,...) and how to perform a
perfect run?

 

Have a good day,

 

Thank you

M.

Literature for Multi-surface plasticity

Submitted by Anonymous (not verified) on

Dear all,

 

Can someone please guide me to comprehensive literature for implementing multi-yield surface plasticity in numerical codes. I am not sure if I, properly, understand the algorithm.

 

Thanks in advance

Best regards,

Hisham

Ductile damage modelling in ABAQUS

Hi all

I am M.Sc. sutdent in Istanbul Technical University and my research subject is comparision of several ductile damage models both computationaly and experimentally.

I am trying to compare ductile damage models such as Freudenthal,Cockroft,Ayada ,Brozzo etc. computationally using ABAQUS and seeking a way to implement these damage models in ABAQUS.

To obtain each models damage result individually should damage model be implemented in ABAQUS or can a regular tensile test results be used for calculation of damage values.
