Abstract Accuracy requirements for machine tools demand an accurate positioning of the tool center point. Due to heat sources, example friction and loss motors, a can undergo complicated deformations during operation. While location mounted sources are known in advance, there also process dependent like hot chips after chip off. Furthermore many material parameters most coupling not exactly, or...

This article addresses a thermo-mechanically coupled problem of thermo-viscoelasticity at finite strains using a monolithic approach. The underlying equations are based on the non-linear transient heat equation, the local equilibrium conditions and the evolution equations of the internal variables. The latter describe the hardening behavior of the material. If the method of vertical lines is ap...

Design of deformation (thermo-mechanical) processes to achieve desired structural response will be addressed. Plastic deformation is assumed to be accommodated through crystallographic slip and reorientation of crystals. Conventional methodologies towards polycrystal plasticity use an aggregate of single crystals and this choice of the aggregate affects the response of the polycrystal. In order...

We consider a thermo-elastic plate system where the elastic equation does not account for rotational forces. We select the case of hinged mechanical B.C. and Neumann thermal B.C., which are coupled on the boundary. We show that the corresponding s.c. contraction semigroup (on a natural energy space) is analytic and, hence, uniformly stable. Because of the boundary (high) coupling, this case of ...

This study presents a coupled thermo-fluid-mechanical peridynamic model to predict composite responses under fire scenarios. Three-layer laminated is modelled by using ordinary state-based thermo-mechanical peridynamics. Both the mechanical deformation and heat conduction are simulated considering thermal degradation properties of composites. The as heat-conducting fluid thermo-fluid based on d...

The amplitude death phenomenon has been experimentally observed with a pair of thermo-optical oscillators linearly coupled by heat transfer. A parametric analysis has been done and compared with numerical simulations of a time delayed model. The role of the coupling strength is also discussed from experimental and numerical results.
