Measuring Deformation Properties4.1 Tension:4.1.1 The procedures outlined in Test Methods E8/E8M,E21, E1450, ISO 6892-1, ISO 6892-2, ISO 15579, a

37、nd ISO19819 explain guidelines for tension testing under variousconditions to determine a materials yield and tensile strengths.All are applicable to materials made additively, but sheet-,wire-, and rod-shaped specimens with small diameters aredifficult to build through an additive process.4.1.2 In

38、the tension testing procedures outlined in TestMethods E292 (for determining a materials rupture strength)and Practice E740 (for determining metal plate yield strength),Test Methods E8/E8Ms methods are followed, but the samplesare first prepared with a notch or surface-crack before subject-ing them

39、to tension. While Test Method E292 is applicable tomaterials made additively, it must be noted that thin specimensmade according to Practice E740 may be challenging to makein some additive manufacturing processes.4.1.3 Two ISO Standards, ISO 26203-1 and ISO 26203-2,describe testing sheet metal, such

40、 as the material used forautomotive bodies, at high strain rates. These standards are notapplicable to materials made additively, because sheet materialwould not be made with such a process.4.2 Compression:4.2.1 The procedures outlined in Test Methods E9 andPractice E209 describe the basic method fo

41、r uniaxial compres-sion testing of metallic samples at various temperatures. Theprocedures are used in determining a materials compressiveyield strength and compression strength. These standards areapplicable to materials made additively, but not all of thesample types (thin sheets) can be successfu

42、lly built through anadditive process.4.3 Bearing:4.3.1 The procedures outlined in Test Method E238 describethe method used to determine bearing yield strength andbearing strength for a rectangular metal specimen containing ahole for a bearing pin. This standard is applicable to materialsmade additiv

43、ely, but the surface finish requirements and somethickness requirements for the specimen may be problematicfor some additive manufacturing processes.4.4 Bend:4.4.1 Practice E209 describes the methods that determinethe limit of plastic deformation allowed in a metallic materialduring bending. The cri

44、terion used to evaluate the quality ofmaterials includes their ability to resist cracking or othersurface irregularities. ISO 7438 includes plastic deformationmethods to evaluate a materials ability to resist cracking. ISO7438 also includes the methodology behind measuring thebending strength, the l

45、imit of elasticity bending, bendingmoments and the bending angle using plastic deformationmethods. These standards are also applicable for metal basedadditive manufactured parts.4.5 Modulus:4.5.1 The following section includes standard test methodsto evaluate elastic moduli and Poissons Ratio. These

46、 testmethods could be used in the determination of elastic proper-ties of metal based AM materials.4.5.2 Tension tests, as described by Test Methods E8/E8M,can be used to determine the Youngs modulus, tangentmodulus and chord modulus of AM structural materials. TestMethod E111 describes how to deter

47、mine the elastic materialproperty based on the tension test (E8/E8M) or compressiontest (E9). This standard also can be used to determine theYoungs modulus, tangent modulus and chord modulus usingthe stress-strain behavior.4.5.3 Poissons ratio is the ratio of transverse strain to thecorresponding ax

48、ial strain, and is an intrinsic material property.This ratio can be useful to further describe any anisotropicbehavior of additively produced bulk materials. Test MethodE132 describes the method to determine Poissons ratio basedon the results of a tension test on a rectangular specimen.4.5.4 Test Me

49、thod E143 describes the procedure for calcu-lating the Shear modulus on specimens with a round shape,F3122 143such as a solid cylinder or a tube. This standard describes theuse of an externally applied torque, and subsequent calculationand determination of the Shear modulus. Shear modulus is ahelpful property used in the design of rotating technical parts,such as, rotating shafts, springs or screws.4.5.5 Two alternative methods to determine the dynamicYoungs modulus, Shear modulus and Poissons ratio aredescribe
