Test Method for Metallic Bone Plates F382, specifically Annex A1. Each plate was manually centered, as described by the ASTM standard using a 120 mm gap between the two support rollers, and a 40 mm gap between the load rollers(1) (Fig.). The plates were tested in bending with the portion of the plate having the minimum section modulus (wider portion of the screw hole) facing the loading direction.(Fig. 2). Displacement-controlled testing was used at 0.1 mm/sec until plastic deformation was reached. Data from the load cell and the LVDT (displacement) was used to establish the bending stiffness of each
bone plate defined by theASTM standard as the maximum slope of the linear elastic portion of the load versus load-point displacement curve (N/mm) (1). Bending moment deflection curves were generated using Microsoft Excel 。A line representing the slope of the bending stiffness was offset by 0.08 mm of displacement (ASTM 0.2% offset method, q = 0.002 x a, where a equals the center span roller distance (40 mm))which was overlayed on the graphs. The point where the bending moment-deflection curves intersected the offset bending stiffness slope was the bending strength reported in N*m as described by the ASTM(Fig.). Bending structural stiffness, defined as the bone plate’s normalized effective bending stiffness that takes into consideration the effects of the test setup’s configuration, of each plate, was determined using the expression: 展开

我先试翻一部分,看看是否满意,如果可以,再翻译其余部分:
F382金属骨板试验方法,专用于附件A1。每个骨板用手工对中,如ASTM标准所述,在两个支撑辊之间留有120毫米间隙,在承载辊之间留有40毫米间隙(如图1所示)。对骨板进行弯曲试验,使板面断面模数最小的部分(螺旋孔的较宽部分)对着加载方向(图2)。在0.1mm/秒毁液的速度下进行位移控制试验,直到达到塑性变形。采用了负载传感器和LVDT(位移)所采集的数据,以确定每个骨板的弯曲刚度。ASTM标准定义的弯曲刚度是载荷的线性弹性部分与加载点位移之间的曲线的最大斜率。应用微消搏软的Excel生成了弯曲扭矩挠度曲线。一条代表弯曲刚度斜率的纤桥物直线由0.08毫米的位移加以偏置补偿(ASTM 0.2%偏置法,q = 0.002 x a,这里a为中心跨距辊间距(40 mm)),这一情况叠加了在图中。弯曲扭矩-位移曲线与偏置弯曲刚度斜率的交点,就是N*m记录的、ASTM所描述的弯曲强度(图1)。弯曲结构刚度被定义为骨板的标准化有效刚度,它考虑了试验装置的构成,对于每个骨板,弯曲结构刚度可以用下面的表达式确定(求出):
