1. Far-field dynamic behavior of a half-space under an inertial strip foundation subjected to a time-harmonic force
Recent research works demonstrated that the interaction between the loads and the carrying structure's boundary which is related to the inertia of the load is an influential factor on the dynamic response of the structure. Although effects of the inertia in moving loads were considered in many works, very few papers can be found on the inertial effects of th

3. A Well Stated Time Domain Integral Representation for Elastodynamic Analysis and Applications
This article discusses three possible ways to derive time domain boundary integral representations for elastodynamics. This discussion points out possible difficulties found when using those formulations to deal with practical applications. The discussion points out recommendations to select the convenient integral representation to deal with elastodynamic p

4. Elementos infinitos para tratamento de problemas da viscoelastodinamica estacionaria pelo metodo dos elementos finitos
The present thesis reports an overview and a numerical implementation of the Finite Element Method (FEM) in wich the so called "infinite elements" are included to model the Sommerfeld s radiation condition or the geometric damping in the stationary response of unbounded (visco-) elastic domains. Initially one dimensional infinite elements are formulated and

5. Slip complexity in dynamic models of earthquake faults.
We summarize recent evidence that models of earthquake faults with dynamically unstable friction laws but no externally imposed heterogeneities can exhibit slip complexity. Two models are described here. The first is a one-dimensional model with velocity-weakening stick-slip friction; the second is a two-dimensional elastodynamic model with slip-weakening fr

6. Slip complexity in earthquake fault models.
We summarize studies of earthquake fault models that give rise to slip complexities like those in natural earthquakes. For models of smooth faults between elastically deformable continua, it is critical that the friction laws involve a characteristic distance for slip weakening or evolution of surface state. That results in a finite nucleation size, or coher
