Zero energy - error is used to optimize combined hybrid axisymmetric finite elements ach8 and rach8 through adjusting the combined factor 數(shù)值實(shí)驗(yàn)結(jié)果表明: ach8是高性能的軸對稱元。
Thirdly , zero energy - error is introduced and used to optimize combined hybrid axisymmetric finite elements through adjusting the combined factor . the influence of combined factor on axisymmetric elements is discussed . finally , the main points of the whole paper are summed up and some further thoughts are put forward 數(shù)值實(shí)驗(yàn)結(jié)果表明:能量協(xié)調(diào)和近似能量協(xié)調(diào)的軸對稱元都具有高精度、不發(fā)生poissonlocking和對網(wǎng)格畸變不敏感的特點(diǎn);經(jīng)過優(yōu)化之后的軸對稱元性能能夠得到進(jìn)一步改善。
