Introduction: Sagittal spinopelvic alignment has been shown to affect loads at the intervertebral joints and has been linked to spine health. Furthermore, the link between degenerative changes and loading of the IVD seems evident with pathophysiological loading widely thought to detrimentally affect the intervertebral disc. If changes in lumbosacral anatomy and kinematics are induced by lumbar ...

Loads cause vertical movements of the foundations all structures. Their magnitude determines building safe operation. A closed analytical solution to problem linear elastic theory for distribution stresses and strains in a homogeneous isotropic foundation has been presented. The article considers calculation stress-strain state an half-plane by method displacement functions. calculating built. ...

On the basis of the theory of three-dimensional elasticity, this paper presents a state space finite element solution for the stresses in cross-ply laminates subjected to combined transverse and in-plane loads. The state space formulation is introduced to solve for through-thickness stress distributions, while the traditional finite elements are used to approximate in-plane variations of the st...

Modelling and simulation of cloth deformation are of great importance in computer graphics and engineering applications. Although many models have been developed, problems still exist. No model so far can accurately describe both motion and deformation of cloth in a unified equation. And the equations for the in-plane deformation of cloth have yet to be developed. In this paper, a model for bot...

In spite of recent progress, soft robotics still suffers from a lack of unified modeling framework. Nowadays, the most adopted model for the design and control of soft robots is the piece-wise constant curvature model, with its consolidated benefits and drawbacks. In this work, an alternative model for multisection soft robots dynamics is presented based on a discrete Cosserat approach, which, ...

A detailed biomechanical model of the low-back musculature that predicts muscle-force distribution in response to external loading is presented. The paper shows that the class of loading tasks that involve an erect posture and an arbitrary load placed on the upper limbs can be described as a loading plane whose axes are the flexion and lateral bending moments. Under these conditions, the indivi...

in this paper, the stability characteristics of single-walled carbon nanotubes (swcnts) under the action of axial load are investigated. to this end, a nonlocal flügge shell model is developed to accommodate the small length scale effects. the analytical rayleigh-ritz method with beam functions is applied to the variational statement derived from the flügge-type buckling equations. molecular dy...

seismic retrofit of masonry slabs in existing steel or masonry buildings has found special significance in current codes as failure of unstable jack arch slabs has been reported as a major reason for collapsing structures in middle east deadly earthquakes. in this paper, three retrofit schemes are investigated and compared. the proposed rehabilitation techniques consist of a single x strapping,...
