New PDF release: Electrical Engineer's Portable Handbook

The 1st version of this identify proved the main profitable of the transportable guide sequence introduced in 1999. geared toward electric engineers and technicians operating in construction energy platforms, the relentlessly useful instruction manual succeeded as an within the box operating software. This new version is necessitated through the recent 2002 model of the nationwide electric Code (NEC).

Example text

As has already been mentioned (sec. 1), in the earliest solutions of shells or revolution, the doubly curved shape was approximated by concial elements with straight side, for which the following displacement fields were adapted by Percy et al (Ref. 37), Stricklin, Navaratna and Pian (Ref. 38) and many other authors (see also Fig. 8). I J=O . (a~+a~s)cosje + lB.. I J=O . . c) 34 These displacement mOdels automatically represent the rigidbody motion of the element with straight meridian, but fail to do so when the meridian is curved.

36) *e K. ; is defined as the condensed element stiffness -J matrix in global coordinates for harmonic j. p~e; is the condensed element equivalent load -J vector in global coordinates for harmonic j. *e -J j K _aa *e P. pj -J _

These functions are assumed to approximate the displacements for each element, and as the finite element subdivision of the structure is made finer, the approximate displacement solution should converge to the exact solution. In order for this convergence to be assured, three conditions must be met. 1 - Displacement functions must be continuous within the elements, and, the displacements must be compatible between 32 adjacent elements along their common boundary. The first part of this requirement is easily met by choosing any continuous function.
