How to use mohr-coulomb criterion to simulate the indentation of BMGs in ABAQUS?

mohr-coulomb criterion

I encounter a big challenge now.

I wanna use mohr-coulomb criterion to simulate the indentation of BMGs in ABAQUS.However, there are many parameters confusing me.

We know the  mohr-coulomb can be written as:

                            τc=k0-ασn

Hi,How to apply seismic accelaration on the BC in abaqus.thank you!:}

Submitted by NewerLi on

I am confused about apply BC of a model in abaqus. because I find that if I apply the accelaration of earthquake on BC, I must remove the fixed constraints applied on BC in previous step in abaqus. so the model become a free body without any constraints.

 any expert can give me some detailed suggestions?thank you very much!^_^

constraint on surface

Hi everyone,

Do you know how to impose in abaqus that all the nodes of a specified surface have the same displacement on U1 for example without specifying a value. think about a traction test of a non homogeneous shell in which we want the edges to remain vertical.

I tried constraint, coupling, U1 but it fixes U1=0

thanks a lot,

Hichem

Crack Length in Cohesive Element (ABAQUS vr 6.7.1) in pure MODE I case

Help! imechanica!

This might not be a smart question to ask, but if any of you can help me, it'd be great.

 I have a DCB (sandwitch specimen) with a cohesive element in the middle. Studying pure Mode I case, displacement is applied at the end of the DCB. Cohesive element works great (it fails when one reaches max separations).  But I am having a difficulity in extracting crack length (i.e. length of failed cohesive element) vs time step. I looked for Damage and Status commend, but it's not promising.  (I'm pretty new to ABAQUS....)

transient analysis problem in ANSYS

ANSYS full transient analysis

i have problem in IMPACT load on beam , whatever is there i mentioned below

i have load (kips) vs time (sec)

at time =0 , load=0 

at time =0.006 , load=5.9

at time 0.056 , load=0

i use funtion editor by linear eqution Y=aX+b

i could not accurate result because of interpolations in ANSYS is differance then the MATHEMATICS. like

As per ANSYS
