Hi everyone

i do adhesive modeling in abaqus but i have a problem

Load - displacement plot show one problam in modeling.

please help to me that resolve this problam.

load-disp Attached on below

thanks

One way of addressing adhesive modeling in abaqus is by using special elements at the interface. A greater challenge is to use the correct mesh size and aspect ratio near the interface to capture the huge gradient (stress concentration) caused by property change in the zone: you may want to see the following publication:

T. Sapanathan, R. Ibrahim, S. Khoddam, and S. Zahiri, Shear blanking test of a mechanically bonded aluminum/copper composite using experimental and numerical methods, Mater. Sci. Eng. A, 2015, 623(0), p.153-164
