ASTM E399 (Standard Test Method for Plane Strain Fracture Toughness for Metallic Materials)
Crack extension under cyclic or sustained forces as by stress corrosion cracking or creep crack growth can be influenced by temperature and environment. It is the responsibility of aastm user of this standard to establish appropriate safety and health practices and determine asstm applicability of regulatory limitations prior to use.
Compact Specimen C T. In addition, the product form should be identified for example, straight-rolled plate, cross-rolled plate, pancake forging, etc. Additional annexes are provided that give specific procedures for beryllium and rapid-force testing. Link to Active This link will always route to the current Active version of the standard. Current edition approved Nov.

Note 1-Plane-strain fracture toughness tests of thinner materials that are sufficiently brittle see 7. General information and requirements common to all specimen types are listed as follows:. Link to Active This link will always route to the current Active version of the standard.
Compact Specimen Loading Clevis. Historical Version s – view previous versions of standard.
The first part gives general information concerning the recommendations and requirements for Ic testing. Summary of Test Method. Fatigue Precracking see also 1.
Work Item s – proposed revisions of this standard. Therefore, compliance with the specified validity criteria of this test method is essential. Fatigue Crack Starter Notches.
This identification is designated by a hyphenated code with the first letter s representing the direction normal to the crack plane and the second letter s designating the expected direction of crack propagation. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not aastm as part of the standard.
The values given in parentheses are for information only. The second part consists of Annexes that give specific information on displacement gage and loading fixture design, special requirements for individual specimen configurations, and detailed procedures for fatigue precracking.
The orientation of the crack plane should be identified wherever possible in accordance with the following systems Guidance on testing elastic-plastic materials is given in Test Method E The effect e39-90 be especially significant for specimens removed from as-heat treated or otherwise non-stress relieved stock, from weldments, from complex wrought parts, or from parts with intentionally induced residual stresses.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Apparatus see also 1. This standard has been approved for use by agencies of the Department of Defense.
The second part is composed of annexes that give the displacement gage design, fatigue cracking procedures, and special requirements for the various specimen configurations covered by this method. The first part gives general recommendations and requirements for K Ic testing.

This strength ratio is a function of the maximum load the specimen can sustain, its initial dimensions and the yield strength of the material. E — 90 Reapproved Standard Test Method for Plane-Strain Fracture Toughness of Metallic Materials1 This standard is issued under the fixed designation E ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. Enviado por Giulio flag Denunciar. Guide B provides supplementary guidelines for plane strain fracture toughness testing of aluminum alloy products for which complete stress relief is not practicable.
The specification of K Ic values in relation to a particular application should signify that a fracture control study has been conducted for the component in relation to the expected loading and environment, and in relation to the sensitivity and reliability of the crack detection procedures that are to be applied prior to service and subsequently during the anticipated life.
