Simulation of Ti-6Al-4V cruciform welded joints subjected to fatigue load using XFEM

Journal of Mechanical Engineering and Sciences, 2019
The stress distribution of cruciform shape welded joints is analyzed by finite element codes ABAQUS. Welded joints with various weld shapes and sizes are investigated to estimate the fatigue life of different joints.

Cruciform specimens used for determination of the influence of T-stress on fatigue crack growth with overloads on aluminum alloy Al 6061 T651

Fracture and Structural Integrity, 2019
The publication presents a cruciform specimen for the determination of cyclic crack growth data under biaxial loading. The design of the specimen with slotted loading arms allows good decoupling between the two loading directions.

Less‐Invasive Capsulotomy Strategy in Hip Arthroscopy: The Gluteus Minimus Sign as a Visual Landmark for the Joint Capsule Based on Cadaveric Analysis

Arthroscopy Techniques, EarlyView.
Abstract Hip arthroscopy requires a capsulotomy to achieve adequate visualization and access; however, an excessive incision can increase the risk of postoperative instability. This technical note describes a less‐invasive capsulotomy technique guided by the “gluteus minimus sign,” a fibrous membrane connecting the main tendon of the gluteus minimus to
