Displacement calculus of the functionally graded plates by finite element method
Alexandria Engineering Journal, 2022 This paper presents our researching results regarding numerical calculus by Finite Element Method (FEM) of the Functionally Graded Plates (FGP). Two approching ways were used: the concept of multilayered plate and the concept of equivalent plate.

Multiaxial high-cycle fatigue modelling for random loading [PDF]
MATEC Web of Conferences, 2019 In this paper, a multiaxial fatigue life prediction model is proposed under general multiaxial random loadings. First, a brief review for existing multiaxial fatigue models is given and special focus is on the LiuMahadevan critical plane concept, which ...

Equivalent stress concept for limit state analysis
, 2022 In this book, criteria for isotropic materials based on the equivalent stress concept are discussed. These criteria are widely applied in the limit state analysis. For general use, they are formulated in the invariants of the stress tensor.

Towards a Highly Sensitive Piezoelectric Nano-Mass Detection—A Model-Based Concept Study
Sensors, 2021 The detection of exceedingly small masses still presents a large challenge, and even though very high sensitivities have been archived, the fabrication of those setups is still difficult. In this paper, a novel approach for a co-resonant mass detector is

Visualization of standard criteria
, 2022 S.123-138The strain criterion, the MohrâCoulomb criterion, the Sdobyrev, PisarenkoâLebedev criterion, and the BurzyÅskiâYagn criterion are often used for approximation of measured data of the plane stress state: They are easy to handle and can be applied
