This study evaluated the effects of instability on the EMG activity of scapular stabilizing and upper limb muscles during exercises with axial and rotational load. Twenty male volunteers (20.9 ± 1.8 years, 174.1 ± 0.04 cm, 73.17 ± 8.77 kg) experienced in strength training participated in a crossover design.

The structural integrity due to problems in the uncertainties of load, the load-carrying capacity of timber structures is of great importance, since peaks of increased loads might occur. One solution of these problems lies in the evaluation of timber structures using non-destructive testing (NDT) methods, and in this special case frequency based ...

Experimental Investigation on the Limitation of Axial Load Level of RC Columns in Seismic Regions
Advances in Structural Engineering, 2006This paper presents an experimental study on the limitation of the axial load applied to reinforced concrete (RC) frame columns with circular, square and diamond sections. Based on seismic tests of 14 large-scale column specimens under low frequency cyclic lateral load, the failure pattern, the hysteresis effects, the skeleton curves, the energy ...

In the design of concrete columns, it is important to provide some nominal flexural ductility even for structures not subjected to earthquake attack. Currently, the nominal flexural ductility is provided by imposing empirical deemed-to-satisfy rules, which limit the minimum size and maximum spacing of the confining reinforcement.

First, a finite element unit cell model of a glass fibre plain weave has been developed via an implicit subroutine. Because of the complex behaviour of fibrous yarns, a user-defined constitutive model needed to be defined. Material properties of yarns in the dry fabric are extracted by fitting the numerical model to experimental data under the uni ...

Influence of Axial Load Level on Performance of Resist Impact on Tubular T-Joint
Applied Mechanics and Materials, 2012Axial load loading on the chord can deteriorate impact performance of tubular T-joint subjected to impact loading on the brace. FEA method was used in this paper to investigate the influence of different axial load level under varied impact energy. The analysis result showed that with the increasing of axial load level, the impact force decreased, and ...

ABSTRACTIn this article, an analytical approach, namely, multi-level residue harmonic balance is introduced and developed for the nonlinear free vibration analysis of axially loaded beams with an internal hinge. The main advantage of this method is that only one set of nonlinear algebraic equations is required to be solved for obtaining the zero level ...

The traumatic C3-C4 level injuries sustained by young athletes and documented by the National Football Head and Neck Injury Registry are discussed. Twenty-eight of 885 (2.8 per cent) injuries involved the C3-C4 vertebrae. Review of these cases reveals that the response to energy inputs at the C3-C4 level differ from that of those involving the upper ...
