Fatigue crack propagation in austenitic stainless steel weldments

Texture characterisation of hexagonal metals: Magnesium AZ91 alloy, welded by laser processing

“…This evolution is in line with mechanical equilibrium. The welded zone exhibits residual traction stresses which are counter balanced by compression stresses in the base metal [34].…”

Fatigue crack propagation in welded joints X70

“…For the design of these assemblies, it is interesting to use the crack propagation laws given by the Linear Elastic Fracture Mechanics [LEFM]. In order to estimate the life of the joints, by calculating the number of cycles needed to propagate a crack from these defects until the rupture [11][12][13][14][15][16][17][18][19][20][21]. Welded structures present a gradient of microstructure and mechanical behaviors from the weld metal to base metal.…”

Experimental fracture resistance study for cracked bovine femur bone samples

“…Several test specimens with different configurations have been employed and suggested in the past for conducting the fracture toughness experiments in different materials. Edge creaked rectangular beam subjected to three or four-point bend loading [13][14][15][16][17][18][19][20][21][22][23], compact test specimen subjected to tension loading [24][25][26][27][28], center cracked Brazilian disc specimen subjected to diametral compression [29][30][31][32][33][34][35], semi-circular specimen containing an edge crack and subjected to symmetric or asymmetric three-point bend loading [36][37][38][39][40][41][42][43][44][45][46], square plate containing center crack and subjected to far field pin loading [47]; edge cracked triangular specimen subjected to bend loading [48][49][50], center cracked ring specimen under compressive loading [51,52] and edge notch disc sample under three-point bend loading [53][54][55]…”
