Hi,
I am running a model (to imitate indentation test) in which I have two parts 1) Deformable part (Considered to be cartilage) and a rigid body. I have given material property to cartilage part using UMAT subroutine. I am giving displacement load of -0.1 to rigid part. I can run the job...
Hi,
I am trying to converge my complex model by trying to play with controls parameters. However, it would be appreciated is someone can help me in understanding what these controls represents?
I have tried to see manual but it would be nice if someone can help me in geeting these controls and...
Hi,
I have a knee joint model which needs to be simulated with Fibril reinforced poro elastic material properties. The model run fine with stiffer material properties but when i run the model with soft material properties (resembling human cartilage tissue), I can these convergence errors. Can...
Hei,
I have two queries. I want to get max value of maximum principal stress at each time point. I want to know that what does this mean? Are these max principal stresses in each node of element and single value is their averages at centroid?
Secondly, I want to get a max value of max...
Hey,
I am working on max and mean values of max principal stress and other parameters of a 3D shape in Abaqus. For taking max values, I am taking peak values (over contact area) from all nodes through each time point. But I want to take max values of parameters better option would be by taking...
Hi,
I am simulating minimum principal strain of knee models. I am getting different graphs for Confidence intervals (showing statistical difference between MRI and X-ray based models) and parametric test graphs(no significant difference). Can someone explain me how to interpret these graphs.
I have to analyze the stress relaxation response (reaction force as a function of time) of a poroelastic,isotropic material (cartilage) that is compressed to 5% of its thickness in unconfined compression. Young modulus is 0.5 Mpa, poisson's ratio as 0.15 and permeability as 1e-8. Nlgeom is off...
Hi,
I need to determine whether it's left knee's or right knee's lateral view and Anterior Posterior view in MRI DICOM data? I have used 3d-Slicer to get DICOM info but is there any way I can determine information about specific views in MRI DICOM?
I have to measure maximum anterior-posterior length of bones (condyles) in X-ray images of knee. I am using ImageJ (Fiji) software for that. However, one problem is that I have to incorporate the phantom of 30mm in the readings as well. How I can do scaling for that in ImageJ?
Need recommendations for constructing 3-D joint models of knee from Planar X-rays..what softwares are best for detailed modelling of knee joints (including ligaments, tendons, cartilage and meniscus) from planar x-rays??? Don't want to use image segmentation methods in MATLAB..not perfect in...

I am modelling foot by segmenting 19 bones of foot in MIMICS and generating mesh in Matics software. Can someone please confirm material properties to be given to foot bones in Abaqus...Most of research papers state 7300 MPa young's modulus, 0.3 poisson's ratio given to foot bones...I am...
Hi all
I am modelling neuropathic foot bones. I have segmented 19 bones via MIMICS software. For meshing I used MATIC and Hypermesh. Now I am trying to simulate the neutral standing position of foot with Abaqus/Implicit (Quasi Static).I considered bones to be elastic and giving material (Young's...
