Frequently, the case of finite strain anisotropy, particularly, the case of transversal isotropy, is applied to biological applications or to model fiber-reinforced composite materials. In this work the multiplicative decomposition of the deformation gradient into one part constrained in the direction of anisotropy (fiber direction) and one part describing the remaining deformation is proposed....
متن کاملSalmonella derby cross-protection study.
An avirulent live (AVL), Salmonella choleraesuis vaccine (Salmo Shield Live [Grand Laboratories, Inc.]) was administered to pigs at weaning or 3 weeks of age. Two weeks after vaccination the vaccinated pigs as well as unvaccinated control pigs were challenged intranasally with a commonly isolated environmental Salmonella serotype, S. derby. At 2, 4, and 6 weeks after challenge, pigs were euthan...

Conventional macro mechanical models and closed form estimates are in many cases not sufficient to appropriately predict the stiffness and strength of composite materials. Composite failure occurs as a result of complex microstructural damage mechanisms, which arise simultaneously with other nonlinear effects in the microstructure. In this contribution we propose an approach, where nonlinear ma...
متن کاملDescriptive study of female roller derby athletes' beliefs about risk factors for injury in roller derby
OBJECTIVES To examine skaters' beliefs about risk factors related to roller derby injuries. DESIGN Qualitative study based on semistructured focus group discussions with female roller derby skaters. METHODS Skaters with varying levels of experience and injury history were invited to participate in focus group discussions. Semistructured focus group discussions were based on the question 'Wh...
متن کاملInstitute for Mathematical Physics Geometrical Formulation of Quantum Mechanics Geometrical Formulation of Quantum Mechanics
States of a quantum mechanical system are represented by rays in a complex Hilbert space. The space of rays has, naturally, the structure of a KK ahler manifold. This leads to a geometrical formulation of the postulates of quantum mechanics which, although equivalent to the standard algebraic formulation , has a very diierent appearance. In particular, states are now represented by points of a ...
