Stresses and deformation in soils
Published in J.A.R. Ortigao, Soil Mechanics in the Light of Critical State Theories, 2020
Another kind of problems presenting an axial symmetry can also be treated in two dimensions. Examples of axial symmetry are: a soil specimen used in laboratory test (figure 2.4b), a tubular pile foundation, a tower, as many other structures. The problem can be reduced to an axi-symmetrical condition with great simplification since: σ2 = σ3.

The basic purpose of the housing is to protect the transducer elements from the testing environment. In the case of contact or immersion transducers, the housing must be a durable and corrosion-resistant material in order to withstand the wear caused by use on other materials. Concerning the geometry of the housing, it should permit easy assembly and it should resist high-pressures (e.g. transducers in flow metering applications generally withstand pressures around 16 bars or higher). A shape with axial symmetry becomes convenient, due to its versatility and ease of fabrication. At the same time, the transducer should be designed with the aim to allow a maximum energy transmission to the propagation medium.

By employing the program ANSYS, the simulation was implemented with an axial symmetry finite element method. The governing equation for heat conduction is (Yang and Tao 2006) where is the density, is the specific heat, is the temperature, and is the thermal conductivity. In cylindrical coordinates, the equation can be written as

The geometric concept addressed is axial symmetry, in the sense of the isometric transformation of the plane in itself, with a line of fixed points (the axis). From this definition, it can be deduced that: axial symmetry preserves the distances and the amplitudes of the angles, and consequently transforms segments into congruent segments and straight lines into straight lines; it is an involutory function [13].
