文摘
- •
A 3D constitutive model for carbon nanotube composites is proposed.
- •
Smooth plasticity is introduced in the carbon nanotubes to mimic the stick-slip.
- •
Eshelby-Mori-Tanaka homogenization is employed.
- •
A finite element implementation is presented in explicit dynamic form.
- •
Simulations show sensitivity of elastic/inelastic response to material parameters.
