As the title suggests, there are two focuses of this discussion theme: impact and cellular materials.

Impact protection can be very practical problems in safety, fires and explosions, oil and gas industry, subsea structures, car manufacturing, nuclear industry, rocket space engineering, etc.

Hi,

I am working on effects of Blast Loading in sandwich composites using Abaqus. I want to incorporate Cohesive behaviour at the interface of the two materials in the sandwich composite structure i am analysing.

Hi Everyone,

 Is is possible to account the surface hardness effect in the tensile testing specimen? If possible, how could it be acomplished?

For instance, I would like to establish the  stress strain curve for the material that used on surface hardened component. Will there be a big change if the surface hardness effect is considered on the tensile specimen?

Please throw some light in this regard.

Thanks

M Gopalakrishnan

hi, i am using Abaqus standard to model a reinforced beam-column connection subjected to a tip load at the end of the beam. 

i first applied a gravity load followed by a tip load at the end of the beam. halfway through the application of the tip load, abaqus standard

stop and give 2 errors.

1) overstraint at certain nodes of my longitudinal reinforcement

2) negative eigen values

When reading papers about visco-plastic or elasto-viscoplastic simulation, all authors only say that the orientation of grain used in the simulation can be randomly generated, and does not refer to how to generate them. I know the orientation of grain can be expressed by Euler angles (phi1, ph, phi2), but can someone give me advice how to generate euler angles?

Dear All,

How do find the inverse of the rectangular matrix.
