Unexpected shear stresses from friction model
2014-10-23 21:06:08 GMT
I am having problems establishing a simple 2D friction model in Abaqus between two rectangular elements (concrete and steel). I am using a vertical contact pressure on the steel surface and a frictional coefficient between the two surfaces of 0.45.
I have defined the frictional coefficient in the contact properties as a "Penalty" and used "Normal" and "Tangential behaviour". At last I have defined a horizontal displacement to the steel part.
When I run the model and plot my results I get a linear displacement curve which is expected but my shear stress also happens to be linear which it shouldn't. Also, the shear stresses are zigzagged and therefore non-monotonic which is a problem. My objective in this model is to get a plot similar to Figure 12-5 in the "Getting Started with Abaqus" manual.
Can you help me?
Note: I am sure that my BCs are correct. I have run the model with 200 increments and used a fine mesh too.
