3.This report,aiming at laminated plates made of composite material,has developed a new finite clement analysis method by establishing stiffness matrixes of isoparametric, solid elements, superparametric shell elements, solid-shell trasi-tion elements and elements with out-element ncdes.
4.2. When other conditions are invariable, casting temperature reduces, the horizontal continuous cast liquid core‘s length shortens, the thinnest solidshell thickness of casting will become thicker.
