The paper introduces a new methodology with a distributed triangle transducer for the strongly coupled simulation of micro electro mechanical systems (MEMS) in ANSYS Finite Element (FE) program.

production of fe-c alloy powders by mechanical alloying was studied. fe and graphite elemental powdermixtures containing 0.8 and 1.5wt.% graphite were mechanically alloyed using a planetary ball mill. thestructural changes of powder particles during mechanical alloying were studied by x-ray diffractometery,scanning electron microscopy and microhardness measurements. for both compositions, mecha...

The effects of flexoelectricity on thermo-electro-mechanical behavior of a functionally graded electro-piezo-flexoelectric nano-plate are investigated in this paper using flexoelectric modified and the Kirchhoff classic theories. Moreover, using the variation method and the principle of minimum potential energy for the first time, the coupled governing nonlinear differential equations of the na...

The present study investigates the effects of process parameters on cold forming an automotive component in AISI 1006 low carbon steel. material formability was characterised up to 250°C. flow behaviour and related thermal distributions during geometrical transformations were analyzed. Coining operations investigated by using a coupled 3D Thermo-mechanical FEM with different die geometries fric...

Pultrusion process is one of the most effective manufacturing techniques for production of composite materials having constant cross-sectional area. Pultruded composite profiles are getting increasingly popular in construction industry as well as in wind energy due to their high strength-toweight ratio, low maintenance cost and high corrosion resistance. Recently, pultruded profiles are foresee...

A mixed semi-analytical cum numerical approach is presented in this paper which accounts for the coupled mechanical and electrical response of piezoelectric, functionally graded (FG) and layered composite hollow circular cylinders of finite length. Under axisymmetric mechanical and electrical loadings, the three-dimensional problem (3D) gets reduced to a two-dimensional (2D) plane strain proble...

This contribution focuses on the development of Model Order Reduction (MOR) for one-way coupled steady state linear thermo-mechanical problems in a finite element setting. We apply Proper Orthogonal Decomposition (POD) computation reduced basis space. On other hand, evaluation modal coefficients, we use two different methodologies: one based Galerkin projection (G) and Artificial Neural Network...

A range of phenomena in the subsurface is characterised by interplay between coupled thermal, hydraulic and mechanical processes deforming structures such as fractures. Modelling dynamics can provide valuable phenomenological understanding, but requires models which faithfully represent involved; these models, therefore are themselves highly complex. This paper presents a mixed-dimensional ther...
