Critical Success Factors for Effective Resident Participation in Community Retrofit: A Systematic Review

Community residents possess first-hand knowledge of the community and effective execution of retrofit methods. Their understanding, acceptance and ultimately participation determine the smoothness of working process and the success of the project. Although the introduction of regulations and policies has increased resident participation in...

Residual fatigue life evaluation of rail at squats seeds using 3D explicit finite element analysis

A modeling procedure to predict the residual fatigue life of rail at squats seeds is developed in this article. Two models are involved: a 3D explicit Finite Element (FE) model to compute the stress and strain at squats in rail, and the J-S fatigue damage model to determine the residual fatigue life on the basis of the computed stress and strain...

Influences of characteristic size of contact bodies on rolling contact

The rolling contact of elastic bodies (upper body and lower body) can be analyzed with the Hertz theory and the Kalker’s model. It is generally believed that the width of the contact area should be much smaller than the characteristic size of each elastic body, to ensure that the half-space assumption is valid. However the definition of “much...

Relating tensile properties with flexural properties in SHCC

Strain hardening cementitious composites (SHCCs) have seen increasing field applications in past decade, yet existing quality control test methods for tensile properties are sometime difficult to implement. This paper presents a new simple inverse method for quality control of tensile strain capacity by conducting beam flexural test. It is shown...
