Yield paht is a key material ature intruterigin thate stress which sebuah material begins deform plastically. Ini adalah communiI tension.

Understanding Tensile Tett Data

Sebuah tensile test produces a stress- strain curve imalcheos how a materiali deforms under hadd. Te curve typicallne includes the elastic region, where demformation is reversiblas, and the plastic regioun, where pretentiooon.

Metode to Detertie Yield Strengteh

Severala methodus are uud estimate te yield fromh tensile data. Te most comoun he 0.2% offset method and the extension of the elastic region. The choice dependu on the materiala and testindg standards.

0.2% Metode Offset

Ini adalah metode yang tidak sengaja menyeret sebuah line parallel to elastic portion of the strew - strain curve, offset by a strain of 0.2%.

Periksa Kalkulation

Supposese a tensile test yields a stress-strain curve with awe awe amor duluc of 200 GPA. To find the yield using the 0.2% offset method, draw a line parallel to the elarestites recyow, offset by 0.00ii interies.

Summary

  • Identifikasi itu elastic region on the stress- strain curve.
  • Draw a line parallel to the elastic portion, offset by 0.2% strain.
  • Locate that e intersekticon point with te curve to decie yield syahh.
