Mood, Recovery-Stress State, and Regeneration
2007Stressful high intensity training periods are necessary to obtain high performance in sports. However, the simple rule ‘the more — the better’ does not apply in this context. A lot of studies clearly showed that systematic recovery periods in the training process are necessary to prevent an overtraining syndrome or staleness, and to obtain overreaching

Eigenstrain controlled deformation- and stress-states
European Journal of Mechanics - A/Solids, 2004The main goal is an applications to proper structural actuation and vibration supression. To achieve exact solution of static and dynamic shape control, the shaped actuators must produce the load strain in form of an eigenstrain with reversed sign. In such an ideal setting, no additional stresses are producted.

In applied mechanics and engineering, materials and structures are generally regarded as continua. This permits us to describe the behaviour and consequences of materials and structures by means of continuous functions. A material is a point (element), and a structure is a body.

In the previous chapter, we have derived the uncoupled differential equations (2.18) and (2.24) for the small deflection theory of plates. Through the first equation the membrane stress distribution for a plane stress problem can be obtained. In this chapter, a boundary integral formulation of this problem, based on the Rayleigh-Green theorem, will be ...

Homogeneous Stress States in Helicoidal Shells
Journal of Applied Mechanics, 1962The fundamental differential sets are presented for the various classes of stress states originated in a right helicoidal shell by loading along helixes or straight generators.

The undisturbed in situ rock before an excavation is already under a certain stress. This stress-state is due to a variety of causes: gravity, stresses due to tectonic motions, the strata orientation, the creep and relaxation produced during geological periods, possible local unloading due to a relatively fast erosion, thermal contractions, etc.

STRESS STATE IN THE COMBINED STRESS TORSION TEST
1968Abstract : An analysis of the stresses in the axial stress-torsion test is presented by considering the gage section as a cylinder undergoing uniform axial deformation with superimposed torsion. Calculation of the stresses requires measurement of the radial deformation and penetration of the plastic region into the notch shoulders.
