第二版2002 弹性力学第十二章 2 Section 12.1 Introduction and Assumptions 引言和假定 A plate is a body bounded by two closely spaced parallel planes and one or more prismatical surfaces normal to the planes
Plate faces--two closely spaced parallel planes Fg.2.1.I Plate edges--prismatical surfaces normal to the plate faces 第二版2002 弹性力学第十二章
第二版2002 弹性力学第十二章 3 • Plate faces--two closely spaced parallel planes • Plate edges--prismatical surfaces normal to the plate faces
Plate thickness--the distance between the two plate faces. It is denoted by t Thin plate-- t<<a t<<b t<min(a, b) 8 Thick plate 第二版2002 弹性力学第十二章
第二版2002 弹性力学第十二章 4 • Plate thickness--the distance between the two plate faces. It is denoted by t. • Thin plate-- t<<a t <<b t<min(a,b)/8 • Thick plate
Plate middle plane The plane parallel to the faces of the plate and bisecting the thickness t is called the middle plane of the plate 第二版2002 弹性力学第十二章
