Good mouring, I am using Abaqus to model a antiplane shear loading of a crack in a plate under planestress condition, therefore i have defined the geometry of the problem with thier mechanical properties and loading; i defind a crack i run the analysis i got this following umbarassing errormessages:
Hi everyone,
I am a working on a cube in abaqus. I had to remove some nodes from the face node sets. To be specific edge nodes. I have defined a function in such a way that after removing them what I have is a list of node labels. I am scripting in python. Can anyone help me in extracting nodes back from nodelabels?
Or is there any better way to remove some nodes from nodelist and get the modified nodelist ?
Thanks
Hello Everyone
I am new to this iMechanica. I am facing difficulty with simulating Groove noise in abaqus.
Can somebody help me out.
Thanks
Hi
I am doing wave simulation on plates with various damages. Guided sinusoidal waves are generated and scattered throughout the plate. To compare the results I am getting FFt of displacement (frequency domain). The one without damage gives me a very smooth FFT while the ones with damage give me a messy FFT ( Please see the attached photo). Is it something to do with filtering or is any thing wrong with my results ?

Hi All,
I am a student working on a project involving the effect of residual stresses in elastic and viscoealstic materials. I have a related question: When an easltic body is heated to a certain temperature (say 400 deg C) and then cooled uniformly to room temperature (20 deg C) with a constant cooling rate "q", does this generate any "un-desirable" (residual) stresses within the elastic body? i.e at a steady state - room temperature, does the final stress state within the body would be non-zero? Else, it would eventually reach a state of zero stresses? How?
Apples and oranges. Each element in a set is a pile containing some number of apples and some number of oranges. Adding two piles means putting them together, resulting in a pile in the set. Multiplying a pile and a real number r means finding in the set a pile r times the amount. We model each pile as a vector, and the set as a two-dimensional vector space over the field of real numbers.

Hi
I am working on a Hyperelastic material. My material model is based on strain energy function (W) = U(J) + W(b)
where, U(J)=k/2*(log(J))^2; k=bulk modulus; J:Jacobian
W(b)= mu/w*(tr(b)-3) ; mu=Shear modulus; tr=trace; b=deviatoric deformation tensor
Overview: The peridynamic formulation is a
spatially nonlocal derivative free model for simulating problems of free crack
propagation.Material points interact through short-range forces and the
formulation allows for discontinuous deformations. Here the short-range forces
are initially elastic and soften beyond a critical relative displacement. We
upscale this peridynamic model to find the macroscopic (a.k.a. small horizon)
limit. It is shown that the limiting macroscopic evolution has bounded energy
given by the bulk and surface energies of brittle fracture mechanics. The
macroscopic evolution corresponds to the simultaneous evolution
of the fracture surface and linear elastic displacement away from the crack
