Hello all, I am trying to obtain the stress history output of a node in my model. To do this I went into the Step module -> Tools menu -> Set -> Create -> Node, and selected the desired node. I then went to the Output menu -> History Output Requests -> Create -> Set, and select the set I just...

Hello all, I have a simple model of a rectangular plate under uniaxial tension stress with a through-thickness central crack in the middle. I am trying to calculate the value of uniaxial stress at which the stress intensity factor K1 at the crack tip exceeds a certain value i.e. fracture...

Good afternoon, I am trying to perform a simple eigenvalue buckling analysis using ABAQUS. The setup is the classic rectangular plate subjected to uniformly distributed compression loads on two opposite edges. All edges are simply supported. The plate model uses shell elements and so I applied...

Hello, I am trying to obtain the buckling stress of a thin plate in ABAQUS modelled using shell elements. I loaded the plate with an edge load (force/length) and I obtain the eigenvalues. Do the resulting eigenvalues represent percentages of the buckling stress OR the buckling shell edge load...

Good afternoon, May someone direct me to a resource for the fracture toughness of structural steel? Perhaps test results from a technical report. Also, does anyone know of a resource for the material constants C and m in the Paris-Erdogan crack growth equation for structural steel? Thanks...

see attached. the tension load is being applied to the far ends. the image is displaying the transverse stresses (S22). notice the compression stresses in the vicinity of the crack. when I do a buckling analysis, the buckling does not seem to occur in that...

the crack is growing across the width, it just initiates at the fillet weld

I mean to say that the edge of the plate with the crack is rotationally restrained. ive been modelling the crack by assigning a seam to a line partition. i'm assuming the crack is already through-thickness

tension buckling will only occur in the presence of some type of flaw such as a crack. usually appears as complex wrinkling. i'm looking at a tension flange stem in an I-shaped plate girder, where fatigue cracks can form at the fillet weld and propagate towards the outer tip of the flange...

Hello, I am trying to obtain the tension buckling modes in an edge-cracked plate using ABAQUS. If I run a regular stress analysis there are certainly compressive stresses in the direction perpendicular to the applied tensile in the region adjacent to the edge crack. However when I run a linear...

Good evening, I am trying to find an expression for the elastic plate buckling coefficient for a plate under pure bending. I would think the expression would be in terms of the width and height, but all I can find are specific values for fixed and pinned boundary conditions. Is this because it...
