Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 89, Iss 927, Pp 23-00201-23-00201 (2023)

A series of numerical material tests based on homogenization theory are carried out to characterize the anisotropic elastoplastic and hardening behavior of thermoplastic resin reinforced in one direction by carbon fibers (UD-CFRTP), and a new constit

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 88, Iss 913, Pp 22-00178-22-00178 (2022)

Thermoplastic resins, which can be used for matrix materials in fiber reinforced thermoplastics (FRTP), have distinctive nonlinear characteristics that depend on temperature and strain rate compared to conventional materials such as metals and thermo

Computational study on temperature-dependencies of relaxation and elastic properties in anisotropic viscoelastic constitutive law for fiber-reinforced thermoplastic resin

Autor: Koji YAMAMOTO, Yoshiteru ISHIBASHI, Masato SOMEMIYA, Norio HIRAYAMA, Kenjiro TERADA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 85, Iss 874, Pp 19-00058-19-00058 (2019)

With use of the numerical material testing (NMT) approach based on homogenization theory, a time-temperature reduction law is proposed for both relaxation and elastic properties in the orthotropic viscoelastic constitutive equation, which is supposed
