This research seeks to investigate the instantaneous effect of beam - column interaction on the axial compressive force in post-tensioned continuous concrete beam.

Dielectric elastomer actuators (DEAs) have been used for artificial muscles for years.

DEA muscles used in bioinspired robotic arms for large deformation and strong force also become desirable for their efficiency, low manufacturing cost, high force-to-weight ratio, and noiseless operation. The DEA-based responsive surfaces in microscale roughness control, however, exhibit limited durability due to irreversible dielectric

The topic of this thesis is a mathematically rigorous derivation of formulae for the magnetic force which is exerted on a part of a bounded magnetized body by its surrounding. Firstly, the magnetic force is considered within a continuous system based on macroscopic magnetostatics. The force formula in this setting is called Brown's force formula referring to W. F. Brown, who gave a mainly physically motivated discussion of it. This formula contains a surface integral which shows a nonlinear dependence on the normal. Brown assumes the existence of an additional term in the surface force which c

The efficiency and accuracy of the method is proved through the numerical implementation applied to a set of test examples.

Streszczenie:

La formabilité des alliages d’aluminium est influencée par l’endommagement dû à la présence de particules (1-10µm). La tomographie X haute résolution (0,7µm) permet de caractériser la morphologie des particules et des pores. La mise en forme à froid est étudiée à travers des essais de traction in situ et des prélèvements d’échantillons de traction plane et de gonflement. L’amorçage est lié à la rupture des particules ou de l’interface particule/matrice. Les porosités croissent par déformation plastique de la matrice. Cette croissance est favorisée par les états de contraintes triaxiaux. L’anis

Streszczenie:

Ce travail de thèse a pour but l'optimisation de forme en forgeage 3D. Les problèmes à résoudre consistent à chercher la forme optimale du lopin initial ou des outils de préforme afin de minimiser une fonction coût F qui représente une mesure de non-qualité définie par les industriels. Ce sont souvent des problèmes multi optima, et le temps nécessaire pour une évaluation de la fonction coût est très élevé (de l'ordre de la journée). L'objectif de cette thèse est de construire un module d'optimisation automatique qui permet de localiser l'extremum global à un coût raisonnable (moins de 50 calcu

Streszczenie:

As the core of virtually all vocal and instrumental composition in the Baroque music, the basso continuo group had an extremely important role in the sacred cantatas by Johann Sebastian Bach (1685-1750). During the Baroque period, the choice of instruments was sometimes indicated by the composer, but frequently the performers had to determine which instruments were most appropriate for the particular environment and context of the music.When performing the sacred cantatas of J.S. Bach, the conductor must identify and make decisions regarding the choices and combinations of instruments for bot
