Bonding of Soft and Rigid Materials
I am workingon a model in which i have a soft layer of material bonded between to rigidlayers of material via cohesive elements following a linear separation-tractionlaw based on a critical fracture energy value I determined from experimentaland numerical work. I have the interlayer and cohesive elements as one partwith a partitioned face and connected to the two adherends viasurface-to-surface ties. I have found that my model runs successfully only ifthe soft interlayer material is made very stiff.
