The finite-element (FE) method is commonly used in biomedical engineering to simulate the behaviour of biological structures because of its ability to model complex shapes in a subject-specific manner. However, generating FE meshes from medical images remains a bottleneck. We present a template-based technique for semi-automatically generating FE meshes which is applicable to prospective studie...

cage roll forming is one of the new methods of cold roll forming process which is widely used for producing erw pipes. in addition to less production cost and time, using cage roll forming provides smooth deformation on the strip. few studies can be found about cage roll forming because of its complexity, and the available knowledge is more experience-based and not science-based. in this paper,...

During their operation, modern aircraft engine components are subjected to increasingly demanding operating conditions, especially the high pressure turbine (HPT) blades. Such conditions cause these parts to undergo different types of time-dependent degradation, one of which is creep. A model using the finite element method (FEM) was developed, in order to be able to predict the creep behaviour...

this deals with the harmonic forced vibration of a circular plate surface bonded by two piezoelectric layers, based on the kirchhoff plate model. the form of electric potential field in the piezoelectric layer is assumed such that the maxwell static electricity equation is satisfied. the differential equations of motion are solved analytically for clamped edge boundary condition of the plate. t...

We assume the function f ∈ L(Ω). We also assume the function u0 has an extension H(Ω), which we denote also by u0. We let the domain Ω to be the L-shaped domain in 2 with vertices V1 = {0, 0}, V2 = {1, 0}, V3 = {1, 1}, V4 = {−1, 1}, V5 = {−1,−1}, and V6 = {0,−1}. It is well-known that the solution u∗ of (1.1) does not necessarily belong to H(Ω) due to the nonconvexity of the domain Ω at the cor...

This study presents a finite element analysis approach to nonlinear and linearized tensegrity dynamics based on the Lagrangian method with nodal coordinate vectors as generalized coordinates. In this paper, without constraints are first derived. The equilibrium equations in three standard forms (in terms of coordinate, member force density, vectors) compatibility equation also given. Then, we p...

This is a review of the current state-of-the-art regarding particular approach to extraction (quasistatic) stress–strain relationship metallic sample from an indentation experiment. It based on application relatively high load (kN range) via large spherical indenter (?1 mm radius), followed by measurement indent profile. profile then used as target outcome for inverse finite element method (FEM...
