Tendon injuries, prevalent in clinical settings, predominantly arise from the disruption of collagen matrix and are typically accompanied by pronounced inflammatory responses perturbations tendon's intrinsic electrical microenvironment. Despite advancements bridging tendon few strategies currently target restoration native microenvironment to facilitate repair. Herein, we fabricated electrospun fibers composed polycaprolactone (PCL) loaded with dopamine (PDA) modified piezoelectric...
Abstract Fatigue crack propagation (FCP) behaviour of 4003 ferritic stainless steel was investigated using infrared thermography. Four stages superficial temperature evolution were observed during the FCP tests: an initial decrease stage, a equilibrium slow increase stage and abrupt stage; thermal model is developed to explain evolution. The experimental results indicate that: when range stress intensity factor (Δ K ) at low level where located in region, thermoelastic effect will be...
Abstract This paper focuses on studying the fatigue crack growth (FCG) characteristics and fracture behaviours of 30 wt% B 4 C/6061Al composites fabricated by using powder metallurgy hot extrusion method. Compact tension (CT) specimens having incisions parallel to direction (T‐D) perpendicular (E‐D) were investigated through FCG tests. Results show that, at low/medium stress‐intensity factor range levels (Δ K ≤ 9), propagation rate in E‐D is lower than that T‐D because elongated C particles...
The temperature evolution in an AZ31B magnesium alloy plate was measured during static and cyclic loading via infrared thermography. relationship between process established. yield limits were predicted. variation on the specimen surface closely related with applied load. initial decrease tension caused by thermoelastic effect, minimum corresponded to limit. During loading, viscous effect plastic work had evolution. limit <1/6 of obtained test.
Based on the infrared thermography method, experiments are carried out to investigate evolution of temperature field extruded AZ31B magnesium alloy specimens under high cyclic fatigue load. The experimental results show that superficial specimen load changes with number cycles. According characteristics surface change, we propose a formula calculate residual life using energy approach. proposed assess parameters (fatigue limit, life, and S–N curve) achieves good for alloy. Furthermore,...
The work-hardening/softening behaviour of AZ31B magnesium alloy during high cycle fatigue was investigated. superficial temperature evolution tests used as a criterion for the different levels work-hardening/softening. microstructures under cycles were observed by transmission electron microscope. Tensile test (with post-fatigue) conducted to quantify which showed that dislocation density after cyclic loading lead tensile strength. specimens with is related microstructures; results indicated...
Fracture toughness of AZ31B magnesium alloy subjected to quasi-static loading was investigated by infrared thermography. The results showed that temperature evolution around the crack propagation path during fracture underwent three stages: initial steady stage, monotonic increase stage and final stage. at beginning II is nearly corresponding initiation unstable propagation. And based on this phenomenon, a method applying thermography estimate proposed. calculated through thermography, which...
In this study, a novel structure of layered Ti-B4C/AA6061 composite with different B4C particles contents was designed and fabricated by pulse current sintering, its microstructure mechanical properties were investigated. It is found that the heterogeneous interface bonds well without voids cracks exhibit homogenous distribution in AA6061matrix. The intermetallic compounds (TixAly) are observed thickness about 1.5 μm between Ti B4C/AA6061 layers. yield strength, ultimate tensile strength...
