ASTM E testing covers the determination of the plane-strain fracture toughness (KIc) of metallic materials by tests using a variety of fatigue-cracked. ASTM E describes the determination of fracture toughness of metallic materials by fatigue tests of precracked specimens. This standard is issued under the fixed designation E; the number 1 This test method is under the jurisdiction of ASTM Committee E08 on Fatigue.

ASTM E Linear-Elastic Plane-Strain Fracture Toughness (K1c) Testing of Metallic Materials

Our application engineers have extensive testing knowledge that you can rely on as we help you decide what system is right for your needs.

Work Item asstm – proposed revisions of this standard. Fatigue Precracking KIc Specimens. Give one of our application astn a call today for help with creating the best budget and r399 plan according astm e399 ASTM E Load versus displacement across the atm at the specimen edge is recorded autographically.

Compact Specimen C T. Details of test apparatus, specimen configuration, and experimental procedure are given in the Annexes. Additional annexes are provided that give specific procedures for beryllium and rapid-force testing.

Measure the crack size after fracture, at mid-thickness and two quarter-thickness positions on the crack front, as well as at the intersection of the crack front with the specimen surface.

Guidance on testing elastic-plastic materials is given in Test Method E Standard and Alternative Astm e399 Configurations. We can configure a test system with accessories astm e399 meet your exact requirements. By working with astm e399 application engineers, you can be confident that TestResources will solve your technical challenges and save you money. ASTM E is used to determine the fracture toughness KIc of metallic materials ast predominantly linearly-elastic, plane-strain conditions.


ASTM E involves the testing of notched astm e399 that have been pre-cracked astm e399 fatigue by astm e399 either in tension or asrm astm e399. Fatigue Precracking see also 1. Metal manufacturing requires the confidence that your incoming raw materials and your outgoing product have the proper strength and ductility needed to astm e399 products that meet your advertised competitive specifications.

Compact Specimen C T. By means of our testing expertise and modular product design, we will help find the testing solution that is right for you. This method uses fatigue pre-cracked specimens having a thickness of 1. It is the responsibility of the user of this standard to establish appropriate safety, health, and e99 practices and determine the applicability astm e399 regulatory limitations prior to use.

Work with us to find the right equipment for your ASTM standard. Our business model utilizes a modular design, that astm e399 like to call ‘Smart Design,’ which enables us to inexpensively build a machine e39 your exact specification.

ASTM E399 Metallic Material Fracture Toughness Testing

Continue the test until the specimen can sustain no further increase in an applied force. The KIc value is calculated from this load atsm equations that have been established on the basis of elastic stress astm e399 of specimens of the types described in this method.

The first part gives general recommendations and astm e399 for Klc testing.

A KIc value is believed to represent a astm e399 limiting value of fracture toughness. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Additionally, astm e399 may consider our wide range of testing fixtures and grips to go with your machine. Standard and Alternative Specimen Configurations.

When astm e399 according to this method, take the metallic specimens and subject them to slowly, or in special elective cases rapidly, increasing crack-displacement force.
