yield load
The purpose of this study was to evaluate the effect of screw placement on the stiffness, yield load, and ultimate load of hamstring graft fixation in the tibial tunnel.
      
Tibial fixation stiffness was greater using concentric screw placement (P >amp;lt; 0.05) although there was no statistical difference in yield load, slippage, or ultimate load.
      
Analysis of yield load, maximum load and stiffness in the single cycle loading test showed no statistically significant differences for hybrid fixation with a 1?mm undersized screw and aperture fixation with a screw matching the size of the tunnel.
      
The BioCorkscrew group also displayed greater yield load during load to failure testing (492.2?±?204?N vs.
      
Elongation after 1,000 loading cycles, ultimate failure load, yield load, stiffness, deformation at the yield point, and mode of failure were recorded.
      
Yield load prediction of nailed timber joints using nail diameter and timber specific gravity
      
Prediction of yield load has nowadays been accepted as the basis for the limit state method of the design.
      
Currently, there are many methods to predict the yield load of timber joints.
      
About 300 Malaysian timber nailed joints were fabricated and tested to obtain the relationship between yield load and maximum load and to propose a new method to predict the yield load of a nailed joint.
      
There seems to be a direct relationship between the yield load and the maximum load.
      
Through the frequency equation a transformation is done to yield load parameter statistics.
      
Each endplate surface was biomechanically tested for regional yield load and stiffness using an indentation test method.
      
The yield load and stiffness from the indentation test of the endplate averaged 139?±?99?N and 156?±?52?N/mm across all cervical levels, endplate surfaces, and regional locations.
      
The posterior aspect of the endplate had significantly higher yield load and stiffness in comparison to the anterior aspect and the lateral aspect had significantly higher yield load in comparison to the midline aspect.
      
There was a significant correlation between the average yield load and stiffness of the cervical endplate and the trabecular bone density on regression analysis.
      
The femoral mid-shaft yield load, stiffness, yield stress, and modulus were, respectively 8%, 13%, 10%, and 14% lower (P >amp;lt; 0.05) in smoke-exposed compared to control mice.
      
Biomechanical structural parameters (ultimate/yield load, stiffness) were measured and apparent material parameters (ultimate/yield stress, modulus) calculated.
      
EP4 KO mice exhibited reduced structural (ultimate/yield load) and apparent material (ultimate/yield stress) strength in the femoral shaft and vertebral body compared to WT (P >amp;lt; 0.05).
      
Using this analysis with an estimate of the ratio of ultimate to yield load in plane strain enables us to predict the maximum work hardening of the part.
      
Quantitatively, however, there was a difference of yield load between the simulation and the experiment, i.e., 2000 N and 8400 N, respectively, likely caused by inaccuracies of material properties of the elements of the finite-element model.
