    • A device (100) of estimating a dose of ionizing radiation absorbed in an intra bone volume. The device comprises a static magnetic field source (101) adapted to generate a substantially static magnetic field in a probing space having a volume of less than 2 cubic millimeter (mm3), the probing space being placed in front of a distal end of static magnetic field source, a micro resonator (104) mounted in adjacent to the distal end, and at least one transmission line which feeds the resonator so as to generate an microwave magnetic field at the probing space and to transmit a signal returned from said microwave magnetic field and indicative of radiation induced paramagnetic defects in said probing space so as to allow a spectrometer (106) to compute a dose of ionizing radiation absorbed in a portion of a bone placed in the probing space according to an analysis of the signal. The static magnetic field source being sized and shaped to maneuver the probing space to overlap with an intra bone volume of the bone.

    • A method for Cosserat Point Element (CPE) modeling of nonlinear elastic materials, utilizing a strain energy function characterizing the response of an eight node 3-D brick element to homogeneous and inhomogeneous deformations, which includes full coupling of bending and torsional modes of deformation. The method includes determining the constitutive coefficients which satisfy bending and torsional modes of deformation for three specific reference element geometries and combining these solutions to obtain constitutive equations for general reference element shapes which ensure that the strain energy remains a positive definite function for all inhomogeneous deformations of the CPE. The constitutive coefficients characterize a generalized CPE model that predicts the response of a 3-D brick element for finite elastic deformations which is free of hourglass instabilities and locking for nearly incompressible materials, thereby providing a robust modeling tool.
