What chemicals should I use to increase the wettability of nanoparticles the nano are carbon tubes, alumina, silica. The adhesives are wooden glue and epoxy.
I have exported a model with all boundary condition and meshes from ansys workbench to abaqus. the imported model has the same meshes and fixed boundary as in the ansys but the applied force did...
