In a novel design of lithium-ion batteries, hollow electrode particles coated with stiff shells are used to mitigate mechanical and chemical degradation.  In particular, silicon anodes of such core-shell nanostructures have been cycled thousands of times with little capacity fading.  To reduce weight and to facilitate lithium diffusion, the shell should be thin.  However, to avert fracture and debonding from the core, the shell must be sufficiently thick.

Hello,

 I need to write a python script that changes the inputs in my MDB file and then runs the abaqus code and gets the output and then goes on with another sets of inputs.

Since I am quite a beginner in abaqus-python scripting, does anyone has any clue how to do this automatically, I mean not changing the inputs in every run manually.

Thanks,

Omid

hello everyone,

I model a reinforced concrete Beam column Joint in ansys .total 32 number of load steps inthe 20th load steps  the below error was appear .

Please guide me That Error What's meaning ?

 The supplied nonlinear material properties produced an incorrect       

 material tangent matrix.  Please check your TB input carefully.  A     

 very small yield stress may cause this failure.

thanks and regards

hello, I am new to abaqus.

I am modeling a soil under seismic exitation with abaqus. the soil is a 2D rectangular elastic model.

As i was creating the mesh, i didnt pay attention and abaqus by deffault took plane stress. Is it a big problem that i work with plane stress or i should restart the calculation with plane strain ?

Thanks,

belhajj.
