Modern analysis of axisymmetric shells with AQUINAS: A MATLAB finite element toolbox

نویسندگان

چکیده

AQUINAS is a specialised MATLAB finite element (FE) toolbox for the nonlinear analysis of axisymmetric thin-walled shell systems, conceived by Authors to recover research functionality once widely available but now largely lost in age supposedly ‘general’ 3D FE software. exploits powerful built-in sparse linear algebra routines with efficient matrix assembly pre-compiled and parallelised C++ code via MEX functionality, as well MATLAB’s extensive visualisation quality-of-life features. In addition making bifurcation buckling calculations shells more accessible wider community, designed facilitate ongoing active development structural Eurocode EN 1993-1-6 governing design metal civil engineering through its capability automate accurate computation nominal resistance capacity curves reference systems.

Analysis of Axisymmetric and Non-Axisymmetric Stretching of Sheet Metals by the Finite Element Method

Stretching process of sheet metals in both cases of axisymmetric and non-axisymmetric is analyzed. A rigid-plastic, normal anisotrop material is assumed and large strain formulation is applied. Triangular elements are used and stiffness equations of elements are obtained from virtual work principle. These nonlinear equations are linearized by Newton-Raphsons method and are solved by Gaussian el...

Finite element stress analysis of a restored axisymmetric first molar.

First molars with full gold crown preparations and a shoulder geometry were ideaIized by an axisymmetric model and analyzed by the photoelastic. as uell as the finite element method. The photoelastic model was constructed in two pieces, the restoration and the tooth with the preparation. The two pieces were then luted together and the model was loaded axisymmetrically with 100 lb; it was stress...

Finite Element Stress Analysis of a Restored Axisymmetric

Experimental stress analysis of dental structures has been a topic of interest during the past quarter century. The object of such research was the determination of stress distribution and improvement of the mechanical strength of these structures. Most of the stress analysis of dental structures was carried out using the photoelastic technique.1-8 A more recent method of stress analysis, origi...
