What is FE???… pls read if you want.. if not jump to another paragraph..
“what is a finite element? The term admits of two interpretations,
as discussed later. For now the underlying concept will be partly illustrated through a truly ancient
problem: find the perimeter L of a circle of diameter d. Since L = π d, this is equivalent to
obtaining a numerical value for π.
Draw a circle of radius r and diameter d = 2r as in Figure 1.1(a). Inscribe a regular polygon of
n sides, where n = 8 in Figure 1.1(b). Rename polygon sides as elements and vertices as nodes.
Label nodes with integers 1, . . . 8. Extract a typical element, say that joining nodes 4–5, as shown in
Figure 1.1(c). This is an instance of the generic element i– j pictured in Figure 1.1(d). The element
length is Li j = 2r sin(π/n). Since all elements have the same length, the polygon perimeter is
Ln = nLi j , whence the approximation to π is πn = Ln/d = n sin(π/n)”
emmm.. baca ke sahabat2 ku… tue baru satu perenggan.. belum baca satu buku.. then belum baca ‘C’ kan.. belum baca ‘bumbung hijau’ lagi.. tue baru baca.. belum nak komen lagi.. nak me’lari’kan program tue lagi.pastu dah ‘lari’ tak sampai tempat lainnnnnnn…. aarrrggghhhh.. so.. dah penat dari benda yg byk2 ‘cacing’ nie.. aku cari benda yg leh buat aku lama depan laptop nie…. hehehhe.. hati tgh2 dup dap2 nie.. takut ‘italian bf’ aku tiba2 bukak pintu.. mampus i.. dah la modelling aku ber’lari’ lintang pukang… kena releks.. kalau tak stress.. hahahhaha…
actually.. apa yg aku nak citer kat next post.. hahahhhaha
