This is a 2D model, using cpe4i plane strain elements for the beams and coh2d4 cohesive elements to model the adhesive bonding the beams. Runs in about 130 secs on my laptop.
DCB - Double Cantilever Beam, from Workshop 4
This is a 2D model using cpe4i plane strain elements for the beams and coh2d4 cohesive elements to model the adhesive bonding the beams. Geometry comes from ASTM D3433.
DCB - ASTM D3433 (tapered DCB, aka TDCB)
This is a 2D model, using b21 elements to model the beams (arms) and coh2d4 cohesive elements to model the adhesive bonding the beams.
This is a 2D ENF model, created from the WS4 DCB model.
ENF - Edge Notch Flexure, parametric input file
This is a 2D SLS model, created from the WS4 DCB model.
