Numerical calculation and finite element analysis for anisotropic elastic properties of carbon fibers: dependence of integration subinterval and mesh size on indentation-derived elastic modulus

Numerical calculation and finite element analysis for anisotropic elastic properties of carbon fibers: dependence of integration subinterval and mesh size on indentation-derived elastic modulus

Article highlights Indentation-derived elastic modulus of highly anisotropic fiber is numerically evaluated. The numerical error in the modulus increases with anisotropy index. Acceptable resolution that returns accurate modulus are proposed.
