    Accuracy of Tensile Testing 304SS Micro-Tubes

    Hi All I am looking to find out if anyone has any input on whether tensile testing a micro-tube (OD 0.66mm, ID 0.48mm) made from 304ss would be accurate enough to derive material properties e.g. tensile modulus, uts, yield stress etc.. Or is it more appropriate to use larger, solid...

    Displacement increment for contact is too big

    Hi all, I am running a static general step, with general contact defined & frictionless intprop. I have a initial inc size of 0.001 and min of 1e-08 with max number of incs set to 1000. The model is a tube deflecting off a bend in a larger tube, and as they come into contact, Abaqus cannot...

    Solid Extruded Tube, collapsing and rippling in Dynamic Explicit Step

    Hi all I have a simple analysis, where a long tube is displaced into a large tube that features a bend. The idea is to look at the stress distributions along the tube as it deforms around the bend. I have been using a dynamic explicit step to run this, using shell geometries to date, and it...

    Assigning different Material properties to the same part

    Hello again I am having trouble assigning different material properties to a single extruded part. I was able to do it successfully to an extruded shell part, via partitioning the part and assigning the props to the two unique sets that were allowed to be created. However when I follow this...

    Problem running simple analysis

    Hi all So im trying to run what I think is a simple problem, that ive described in a previous thread. All I want to do is advance a tube into a small long tube, into a large tube with a bend, and measure the deflection of the small tube as it deforms around the inside curve of the large tube...

    How to displace an entire part?

    Hi all I have a part (long tube) that I want to displace and deform around a bend. Think of it as inserting a catheter into an artery and it bending around a radius of curvature. How can I do this in Abaqus CAE/Explicit? I am new to learning this (have done some problems in college, and have a...
