The vibration characteristics of a maxillary central incisor were investigated by using the finite element method (FEM) according to nonlinear behavior of the human periodontal ligament (PDL). The effect of alveolar bone loss was also studied to obtain the relationship between the vibration property of the tooth in the periodontal system and the level of(More)
Molybdenum (Mo), a bcc metal with a melting point of 2,610°C and a density of 10.22 g/cm, is an important refractory metal. The refractory properties of molybdenum reflect the high strength of interatomic bonding resulting from the overlap of the 4d-orbitals and the number of bonding electrons available (1). The melting point of molybdenum is exceeded only(More)
In this paper, a constitutive model proposed by Cheng and Nemat-Nasser [Acta Mater. 48 (2000) 3131] is extended to describe both the dynamic and quasi-static stress±strain response of a commercially pure molybdenum over the temperature range 300±1100 K. Experimental results of Nemat-Nasser et al. suggest that molybdenum behaves plastically di€erently at(More)
