In practical application situations, a carbon fiber-reinforced polymer (CFRP) is often subjected to complex dynamic loadings. The effect of the strain rate on mechanical properties very important for CFRP design and product development. this work, static tensile with different stacking sequences ply orientations were investigated. results showed that strengths laminates sensitive rate, while Young's modulus was independent rate. Moreover, related orientations. experimental effects cross-ply...
Weld lines are a common defect generated in injection molding, which apparently affects the performance of final products, but available reports on carbon fiber-reinforced thermoplastics still rather few. In this study, effects temperature, pressure, and fiber content mechanical properties weld were studied for nylon (PA-CF) composites. The line coefficient was also calculated by comparing specimens with without lines. tensile flexural PA-CF composites significantly increased rise lines,...
To estimate the fatigue life of lightweight automotive structures in compliance with top-down design principles, there is a need for an accurate adhesive joint prediction method that compatible industrial finite element modeling practices. This paper proposes to split analytical J-integral solution based on fracture mode joints. The I and II J-integrals correspond opening sliding bonded joint, respectively. By splitting introducing concept mixed ratio, improved approach estimating presented,...
This study proposes a parameterized model of uniaxial symmetry non-circular hole, to improve conventional circular bolt clearance holes on turbine disks. The profile the consists eight smoothly connected arcs, radiuses which are determined by 5 design variables. By changing variables, hole can be transformed accommodate different load ratios, thereby improving stress concentration area near and that disk. is optimized based finite element method (FEM), in maximum first principal taken as...
Abstract To realize robust structural design, the effects of adhesive fillet, overlap length and unbonded area in adhesive‐bonded joints need to be fully understood incorporated into a fatigue life estimation method. In present work, both static experiments are performed on six types illuminate these systematically. A straightforward total evaluation method is proposed address effects. statistical crack initiation model established based data bulk specimens. Growth calculated using...
Fatigue and corrosion damage are the major concerns of automotive adhesive joints, yet literature reports few works about in situ fatigue durability joints corrosive environment. This study presents an investigation on single lap by test. The were manufactured with commercial coated AA5754-O aluminum sheets bonded a toughened epoxy structural adhesive. An chamber was designed employed to simulate humid environment spraying 5% saline solution or distilled water mist around joints’ overlap...
Purpose: This study aimed to investigate whether the presence of a mesial cantilever influences biomechanical behavior and screw loosening in fixed partial dentures (FPDs) with distally tilted implant atrophic posterior maxilla where best place distal implant.
An integrated adhesive material model calibration method is proposed for adhesively bonded joints' deformation and progressive failure simulations under mixed loading modes. In this method, a surrogate trained to express the intrinsic numerical relationship between key parameters (e.g., yield normal stress shear stress) simulated load-displacement curves of specimens. The parameter process multiple conditions described as multi-objective optimization problem. To minimize curve errors among...
The microstructure and tensile failure evolution of AA5754O aluminum alloy CMT joints were investigated in this study. First, the properties observed using a hardness test metallographic test. studied situ CT tests. defects heat-affected zone mainly composed pores with large sphericity. softening was due to decrease effective bearing area increase number defects. There shrinkage sphericity less than 0.6 fusion continuous growth combination pores, which led area. Meanwhile, variation process...
