Damage in composite materials occurs at multiple scales, from matrix cracking and fiber/matrix debonding to ply delamination, and is complicated due to the different failure mechanisms interacting with the composite microstructure. Recent progress in the development of advanced techniques for structural health monitoring (SHM) has been aimed at techniques capable of sensing damage in situ and i...

A multi-scale methodology that includes microscale finite element simulations, physical experiments, and a macroscale phenomenological model was used to determine the appropriate first-order influence parameters relating to void/ crack nucleation. The finite element analyses were used to examine the role of seven independent features (number of silicon particle sites, uniformity of particle siz...

The damage accumulation failure scenario is one of the most prominent ones of cemented THA reconstruction, and involves the accumulation of mechanical damage in materials and interfaces due to repetitive dynamic loading eventually resulting in gross loosening. This study addresses this scenario by combining finite element techniques with the theory of continuum damage mechanics, to analyze the ...

OBJECTIVES The objectives of this systematic review were to assess the 5-year survival of resin-bonded bridges (RBBs) and to describe the incidence of technical and biological complications. METHODS An electronic Medline search complemented by manual searching was conducted to identify prospective and retrospective cohort studies on RBBs with a mean follow-up time of at least 5 years. Patient...

OBJECTIVES To clinically evaluate the prevalence of buccal caries and white spot lesions (WSLs) at debonding in governmental and private orthodontic patients, using the International Caries Detection and Assessment System (ICDAS-II) and the DIAGNOdent Pen, and to study the correlation between the two methods. MATERIALS AND METHODS A cross-sectional study was carried out on the nonextracted pr...

Present study aims to investigate the effect of stress state and loading rates on damage mechanisms in a DP1000 steel using welldesigned series experiments. A specimen family comprising central hole, in-plane shear plane strain samples is applied characterise under well-controlled states. The optimization geometries achieved finite element simulations. To assess influence rate, quasi-static, in...
