plane lamina 中文意思是什麼
plane lamina
解釋
平面薄片-
An experimental program which includes lots of unidirectional laminae is conducted using t300 / bmp - 316 material for researching the static and fatigue behaviour of the unidirectional ply. the experimental research for mechanical behaviour of a unidirectional lamina is to set up expressions of the normalized fatigue life, the residual strength degradation and the residual stiffness degradation of a unidirectional ply in the longitudinal, transverse and in - plane - shear directions, which also verifies the fact of nonlinear shear stress - strain behavior of a unidirectional ply in the 1 - 2 planes
其中:分別對材料t300 / bmp - 316單向層合板縱向、橫向及面內剪切靜載力學性能及疲勞特性進行了試驗研究，並採用最小二乘法擬合得到各主方向正則化疲勞壽命表達式，以及單層板各主方向疲勞加載剩餘剛度退化表達式及剩餘強度退化表達式;試驗同時驗證了單向層合板1 - 2面上明顯的剪切應力應變非線性關系。 -
The distortion of in - plane fibers is considered to be the main reason for the effect of stitching on the in - plane mechanical properties, and the fiber distortion region, the resin - rich pocket and the through - thickness reinforcement section are taken into account. the fiber misalignment angle and the inhomogeneous fiber volume fraction caused by stitching have been determined within the lamina. the elastic constants of a lamina are calculated using a micromechanical model, then the constitutive equations of the stitched composite laminates can be composed
從縫紉孔附近纖維變形的細觀結構出發，建立的纖維彎曲模型，以面內纖維的彎曲變形作為縫紉影響層合板面內力學性能的主要原因，同時考慮了纖維變形區、厚度增強區以及樹脂富集區的影響，得到單向板內任意一點處的纖維偏轉角和纖維體積百分含量。
