Effect of additional grip on tensile strength of non-ferrous materials for ship

Non-ferrous material frequently slipped failure, hard clamp surface press slip occurs, and non-metal lacks a rigidity hold for the clamp, resulting in or break before limit strength. So as efforts to prevent this problem are carried out from additional grips reduce occurrence of slips obtain an increased testing accuracy. Additional grip designs created using sizes specified by ASTM D638. receives pressure equal 106.4 MPa, so deformation, stainless is chosen grip. This test determine quality materials used ship. In research, was developed improve technology test. Continued data analysis conclusion were obtained that tensile tools has high success rate. Rubber fibre-reinforced plastic (FRP) specimens have rate 60%. The factor causing low wood fibres irregular direction, uncertainty makes results unsuccessful. From process, ultimate stress value without lower than tests with grips. rubber 51.92%, FRP 16.40% more average value, moreover, strength HDPE also elongated accepted rules.
