Posterior tibial slope is linearly related to anteroposterior shift of the tibiofemoral contact mechanics: A biomechanical study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate the changes in tibiofemoral contact mechanics following an infra‐tubercle slope‐modifying osteotomy. Methods An infra‐tubercle slope‐modifying osteotomy was performed on eight fresh‐frozen cadaveric knees and fixed with an external fixator, which allowed for accurate slope adjustments from 15° to 0° in 5° increments. The

Knee joint line obliquity alters lateral meniscal root tension, tibiofemoral subluxation and compartment‐specific contact pressures

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The objective was to measure effects of joint line obliquity (JLO) on meniscus posterior root tension, tibiofemoral subluxation and contact pressures. It was hypothesised that a medial JLO would increase medial meniscal (MM) root tension, medial tibiofemoral subluxation and medial compartment contact pressure, and vice versa for ...

Reduced patella medialization in valgus and varus knees using a KA‐optimized femoral component in kinematically aligned TKA

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellofemoral complications after total knee arthroplasty (TKA) are linked to femoral component design and trochlear alignment. This study compared the effects of a kinematically aligned (KA)‐optimized femoral component versus a standard design on patellofemoral kinematics, contact mechanics and quadriceps function, using native knee ...

Computed tomographic arthrography of the coxofemoral joint in horses

Equine Veterinary Education, EarlyView.
Summary Background Investigation of pathology relating to the coxofemoral joint (CFJ) in horses includes intra‐articular analgesia and diagnostic imaging using ultrasonography, radiography, scintigraphy and computed tomography (CT). While CT arthrography has been described for diagnosing intra‐articular ligament and cartilage injuries in different ...

Biaxial Constitutive Relation and Strength Criterion of Envelope Materials for Stratospheric Airships

Aerospace
The performance upgrading of stratospheric airships hinges on breakthroughs in the mechanical properties of envelope materials. As a multi-layer composite, the envelope’s load-bearing layer exhibits orthotropic and nonlinear mechanical behaviors owing to

Axial and Biaxial Fatigue Behavior of 6061‐T651 Cold Metal Transfer Welded Joints

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Lightweight aluminum structures in transportation systems are increasingly exposed to complex service loading, yet the fatigue performance of welded joints is still predominantly assessed using uniaxial data. In this work, the axial and biaxial fatigue behavior of 6061‐T651 aluminum alloy joints produced by cold metal transfer (CMT) welding is

Surrogate-Based Shape Optimization of a Cruciform Specimen for Biaxial Testing of Microparticle Reinforced Epoxy Adhesives

Applied Sciences
Reliable determination of the in-plane biaxial mechanical behavior of particle-reinforced composite adhesives under multiaxial stress conditions requires cruciform specimen geometries that achieve high stress uniformity in the measurement zone.

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

Journal of Anatomy, EarlyView.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

Numerical study of fatigue crack initiation and propagation on optimally designed cruciform specimens

Procedia Structural Integrity, 2016
AbstractA new generation of smaller and more efficient biaxial fatigue testing machines has arrived on the market. Using electrical motors these machines are not able to achieve the higher loads their hydraulic counterparts can, and therefore the cruciform specimen needs to be optimized.

An integrated study on the optimal shape design of cruciform specimen used in equibiaxial tensile test of a hyperelastic material [PDF]

IOP Conference Series: Materials Science and Engineering, 2017
To conduct a finite element analysis of a material exhibiting large deformations (hyperelastic material), hyperelastic Ogden model is commonly used. However, hyperelastic Ogden model requires several tensile tests data including equibiaxial tensile test during the parameter identification. In equibiaxial tensile test, although cruciform-shaped specimen
