1, of substantival term (1) isotropy: A kind of character that material function and direction have nothing to do. (2) anisotropy: A kind of character that material function differs because of direction and changes. (3) orthogonality anisotropy: Material has the character with 3 mutual and perpendicular stretch planar semmetry, these planar normal direction call material advocate direction. (4) is transverse isotropy: Have the stuff of orthogonal anisotropy character, if have an isotropy plane when, say for transverse isotropy. One-way composite material has this kind of character namely. (5) coupling: Outside force causes not as corresponding as its copy metabolic effect to call coupling. (6) pulls cut the coupling, coupling that pull a turn, crankle coupling: Point to respectively by stress causes the coupling that cuts meet an emergency, by stress causes the coupling that curves meet an emergency; You Wanju causes the coupling that turns round meet an emergency. 3 person all be anisotropy stuff place peculiar. (7) axis: With material advocate the referenced reference axis of directional coincide. (8) slants axis: Expect with compose advocate direction not coincide, have the referenced reference axis of horn of a deflexion. (9) lay up: Composite material is made in an one-way belt or fabric call a lay up, it is composite material is made in a main unit. (10) layer plywood: By one-way or the composite material that squelch to lay up more and becomes board. (11) spreads to horn () of lay up horn: The fiber direction of each lay up and make an included angle between axis of referenced coordinate X, to fiber direction by X axis anticlockwise corner coming back is spent for lay up horn. (Group of 12) lay up: One group has the successive lay up of horn of identical lay up. (13) lay up is ordinal: Spread what all sorts of differring have to spread the lay up to horn in sticking to arrange order. (14) child layer plywood: One is in inside layer plywood for many times reduplicative is combined to lay up more. (Plywood of 15) symmetrical layer: All lay up reachs his all sorts of character and parameter are opposite at board the layer plywood of semmetry of the face in geometry. (Plywood of 16) balanced layer: All sorts of character of lay up and parameter are identical, the shop is to horn - the layer plywood with the lay up equal number of θ and θ , and the 0° layer that can contain aleatoric amount and 90° layer. Be like [45° ／ - 45°] , [90 ／ of ／ of 0 ／ 45° - 45°] . (Plywood of layer of 17) balanced semmetry: Namely balanced symmetrical layer plywood. Be like [45° ／ - 45°] . (Plywood of 18) orthogonality layer: Have the two-way layer plywood of 0° and 90° lay up only, be like [0° ／ 90°] . (19) is inclined the plywood that hand in a layer: Contain only - the two-way layer plywood of θ and θ lay up, be like [45° ／ - 45°] . (20) allows isotropy board: The symmetrical layer plywood with the stretch identical constant of each direction inside the face, be like [60 ／ of 30 ／ one 60] of one 30 ／ . (21) N ／ 4 plywood: Have way of 4 lay up, 45°(of each other be apart namely N ／ 4) , and the symmetrical layer plywood that group of each lay up can have aleatoric ply. Be like [45 ／ of 0 ／ 90 ／ 0] of one 45 ／ . (Plywood of 22) general layer: Basically be to point to asymmetrical layer plywood, still can include to have different layer board combined-type layer plywood of composition, or the Composite layer plywood that has composition of material of different lay up. Be like [45 ／ of 0 ／ 45 ／ of one 45 ／ 90 ／ 0] . (The stress between 23) layer: Outside the heft of 3 faces internal stress that divides layer board, the edge arises on the interface between two lay up, the 3 stress heft that concerns with ply direction, zx, τzy, σz. Among them two cut heft to weigh the shearing stress between the layer, also weigh transverse shearing stress. (24) invalidation criterion: Below condition of meet an emergency of complex stress — , the criterion of material invalidation. (25) is allowable value: The material property that allows to use in computation is worth, decide by certain test data. (26) intensity compares: The intensity limit of material and structural place suffer corresponding stress than. 2, the notation of layer plywood (plywood of 1) general layer: The direction of each lay up uses the included angle of fiber and X axis to show, each other use departure of “ ／ ” , use entirely [] on draw together, press draw up by the order outside fall and go up or sticking film to face, be like [45 ／ of 0 ／ 30 ／ 90] of one 45 ／ . (Plywood of 2) symmetrical layer: Draw up only half, draw together extra adds suffix S. If be odd layer, one ” of “ carrying mark on the head is added on lay up of the face in semmetry. Be like [0 ／ 90]s or [45 ／ of 0 ／ 90]s. (3) has when repeating lay up continuously: The number of plies of successive lay up goes out with the designation below the number, be like [90] of ／ of 0 ／ 45n. (4) pulls by much stature layer when forming: Child layer board heavy complex number uses the designation below the number, be like [0 ／ 90]n. (The layer plywood that 5) spreads by fabric: The classics abb direction of fabric uses “()” to show, be like [(earthy 45) ／ (0, 90)] . (6) is jumbly plywood of composite material layer: Express with suffix respectively. C: Carbon fiber, k; Fiber of fragrant black silk ribbon, g: Fibre glass. Be like [0C ／ 45G] . (7) interlining board: Express to place core with C, suffix number states the millimeter of the ply that place core is counted, ibid of notation of face plate lay up, be like [90 ／ of 0 ／ Cn] .
