This paper presents the effect of load carrying (position and weight of load) on the maximum peak values of traction coefficient between shoe sole and floor during walking on level walkway. Gait experiments were conducted by five healthy male adult participants walking on the force plates with carrying the loads. Each subject was tested at step length of 0.75 m and at walking speed of 1.4 m/s. ...

The loading path the fault experiences is often neglected when evaluating its potential for reactivation and related seismic risk. However, stress history affects zone compaction dilation, thus mechanics. Therefore, in incohesive cores that could dilate or compact, role of not be ruled out. Here we reproduce laboratory different tectonic paths reverse (load-strengthening absence significant flu...

Progressive spondylolisthesis may occur in adults with isthmic spondylolysis with an estimated incidence of 20%. This biomechanical study showed that in adult spines with bilateral L5 pars fractures, an anterior slip of L5 depends on the extent of the load-bearing deficiency of the disc and the presence of shear force across L5-S1. A combination of disc degeneration and muscle dysfunction may b...

This paper describes the theoretical development and experimental evaluation of a navigation system for an autonomous load, haul, and dump truck (LHD) based on the results obtained during extensive in-situ field trials. The particular contributions of the theoretical work are in designing the navigation system to be able to cope with vehicle slip in rough uneven terrain using information from i...

The focus of this research is the stress laminated timber cellular deck. The testing program has involved application of loads that modelled both the design serviceability and design ultimate conditions, and identified slip and load redistribution mechanisms, which occur at the limit state of linear composite behaviour. This paper presents a summary of the results of this testing and discusses ...

Knots are fascinating topological elements, which can be found in both natural and artificial systems. While in most of the cases, knots cannot be loosened without breaking the strand where they are tightened, herein, attention is focused on slip or running knots, which on the contrary can be unfastened without compromising the structural integrity of their hosting material. Two different topol...

Recent observations of an association between forearc basins and slip during subduction thrust earthquakes suggest a link between processes controlling upper plate structure and seismic coupling on the subduction-zone thrust fault. We present a mechanism for the formation of these basins where sedimentation occurs on landward-dipping segments of the subduction wedge, which itself is actively gr...

A comparative study of fracture in Al is carried out by using quantum mechanical and empirical atomistic description of atomic interaction at crack tip. The former is accomplished with the density functional theory (DFT) based Quasicontinuum method (QCDFT) and the latter with the original Quasicontinuum method (EAM-QC). Aside from quantitative differences, the two descriptions also yield qualit...

We present two geometric descriptions of the frictional properties of a rigid body sliding on a planar surface. The limit surface LS, from classical plasticity theory, is the boundary of the set of all possible frictional forces and moments that can be sustained by the frictional interface. Zhukovskii’s moment finction is the frictional moment as a function of the instantaneous center of rotati...

The main objective of this study is to provide a parametric evaluation of the pull-out work of smooth steel fibers embedded in cementitious matrices. The various parameters controlling the behavior of the bond stress versus slip relationship are analyzed; their effects on the entire pull-out load versus slip response and the corresponding pull-out energy up to full debonding and~or up to total ...
