A one-dimensional ubiquitiformal constitutive model for a bimaterial bar is proposed in this paper. An explicit analytical expression for the effective Young modulus is then obtained, which, unlike the fractal one, leads to a continuous displacement distribution along the bar. Moreover, numerical results for concretes are calculated and found to be in agreement with previous experimental data. In addition, some previous empirical and semi-empirical constitutive models are also examined, which shows that each of these models can correspond well to a ubiquitiformal one under a certain complexity.
A theoretical method is proposed for determining the relation between the potential dip-slip and strike-slip of the fault. This method is based on strike separation and allows for estimating the minimal displacement value along the fault for its sector where the strike separation was measured. Moreover, the value of total slip for different scenarios of the fault movement can be estimated using this method. Such assessments can be very useful in disproving hypotheses by comparing the obtained total slip values with geological data. The usability of this method is shown at the example of analysis of displacements along the Łysogóry Fault in the Holy Cross Mts.

The author uses a holographic interferometry technique to measure the displacement of cervical spine fixators when applied to a section of cadaveric spine which is loaded in bending and torsion. The analysis was undertaken to assess the effect of stabilizers implanted in the cervical section of the spine on the load bearing mode and the rigidity relationships.
