ASTM D638-14 Type IV横向和纵向拉伸试样棒Re**份爱 上传90.91 KB 文件格式 zip ASTM是美国材料和试验协会的简称,指的是该组织所发布的一系列材料测试方法和标准。其中ASTM D638是ASTM所制定的用于测量塑料拉伸性能的标准测试方法。拉伸指标是衡量材料抗拉强度或材料在受力下延伸程度的能力的参数。通过进行拉伸试验...
This paper utilizes a large pool of 47 user-assembled 3-D printers to quantify the mechanical property variations of ultimate tensile strength (UTS) and yield strength of FFF printed components using ASTM D638-14 horizontally-oriented Type I and IV geometries for poly lactic acid (PLA). The ...
OPTIMISATION OF PROCESS PARAMETERS ON TENSILE STRENGTH OF 3D PRINTED POLYLACTIC ACID (PLA) PARTS: ASTM D638 TYPE -- IV Purpose: The purpose of this study is to optimize the influence of 3D printing processing parameters on the ultimate tensile strength of 3D printed Polylac... MK Akpakpavi,...
Designation: D638 – 10 Standard Test Method for Tensile Properties of Plastics1 This standard is issued under the fixed designation D638; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number...
The ASTM D638 standard covers the determination of tensile properties including thetensile strengthof unreinforced and reinforced plastics. Other common standards used to test tensile strength areASTM E8/ASTM E8Mfor metals,ASTM D412for rubber and elastomers, andASTM D3039fiber-reinforced compo...
It should be noted that the ASTM D638 standard can have different variants, such as D638 Type I, Type II, Type IV, etc., each of which has different requirements for specimen size and test conditions. The applicable version and variant of the standard should be carefully read and followed...
