Recent Finite Element Analysis (FEA) modeling of a Standard shear plate of Navy II type PZT-based ceramics was carried out based on the full matrix material characterization Material coefficients in the linear range, including all losses, were obtained by an iterative automatic method from impedance measurements at resonance. FEA modeling has shown that the shear plate used in the standard char...

[Purpose] Physical therapists, osteopathic practitioners, and chiropractors often perform manual tests to evaluate sacroiliac joint (SIJ) mobility. However, the available evidence demonstrates an absence of reliability in these tests and in investigations with kinematic analysis. The aim of this study was to verify the three-dimensional kinematic reliability in SIJ movement measurements. [Subje...

The objective of this dissertation is the design and analysis of iterative methods for the numerical solution of large, sparse linear systems. This type of systems emerges from the discretization of Partial Differential Equations. Two special types of linear systems are studied. The first type deals with systems whose coefficient matrix is two cyclic whereas the second type studies the augmente...

Over the past decade, many computational studies have explored the mechanics of normal indentation. Quantitative relationships have been well established between the load–displacement hysteresis response and material properties. By contrast, very few studies have investigated broad quantitative aspects of the effects of material properties, especially plastic deformation characteristics, on the...

National Bureau of Standards Gaithersburg, MD 20899 Studies of transient wave propagation in plates were carried out to establish a basis for the impact-echo technique as a nondestructive test for flaw detection in concrete. The surface displacements caused by stress waves generated by point impact on a plate were calculated using both the Green's function solution and the finite element method...

BACKGROUND Ultrasonography has been widely applied for in vivo measurements of tendon mechanical properties. Assessments of human Achilles tendon mechanical properties have received great interest. Achilles tendon injuries predominantly occur in the tendon region between the Achilles-soleus myotendinous junction and Achilles-calcaneus osteotendinous junction i.e. in the free Achilles tendon. Ho...

objective(s): reliability measures precision or the extent to which test results can be replicated. this is the first ever systematic review to identify statistical methods used to measure reliability of equipment measuring continuous variables. this studyalso aims to highlight the inappropriate statistical method used in the reliability analysis and its implication in the medical practice.   m...

residual stress measurement has gained interests among researchers for many years due to its great influence on the structural integrity. slitting method is one of the destructive techniques that relies on the introduction of an increasing cut to a part containing residual stresses. similar to all other mechanical strain relief techniques, slitting also suffers from its shortcomings during the ...
