Displacement calculus of the functionally graded plates by finite element method

open access: yesAlexandria 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]

open access: yesMATEC 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 ...

Towards a Highly Sensitive Piezoelectric Nano-Mass Detection—A Model-Based Concept Study

open access: yesSensors, 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detection of exceedingly small masses still presents a large challenge, and even though very high sensitivities have been archived, the fabrication of those setups is still difficult.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

Ductile failure analysis of epoxy resin plates containing multiple circular arc cracks by means of the equivalent material concept

open access: yesInternational Journal of Mechanical and Materials Engineering, 2021
AbstractDuctile failure of polymeric samples weakened by circular arc cracks is studied theoretically and experimentally in this research. Various arrangements of cracks with different arc angles are considered in the specimens such that crack tips experienced the mixed mode I/II loading conditions.

A similarity law for stressing rapidly heated thin-walled cylinders [PDF]

open access: yes, 1952
When a thin cylindrical shell of uniform thickness is very rapidly heated by hot high-pressure gas flowing inside the shell, the temperature of material decreases steeply from a high temperature at the inside surface to ambient temperatures at the ...

The Microwave Thermal Thruster Concept [PDF]

open access: yes, 2004
The microwave thermal thruster heats propellant via a heat-exchanger then expands it through a rocket nozzle to produce thrust. The heat-exchanger is simply a microwave-absorbent structure through which propellant flows in small channels. Nuclear thermal
