Bi-Linear Bond-Slip Modelling for 1-D Tension Stiffening Behavior of a RC Element
Infrastructures, 2022 Cracking is an inherent characteristic of a reinforced-concrete (RC) element subjected to tension or bending. The crack width growth with loading depends on the rebar-concrete bond behavior.

Multi-cracks Modeling in Reflective Cracking [PDF]
, 2012 Reflective cracking is a major concern for engineers facing the problem of road maintenance and rehabilitation. The problem appears due to the presence of cracks in the old pavement layers that propagate into the pavement overlay layer when traffic load passes over the cracks and due to the temperature variation. The stress concentration in the overlay

Stress corrosion cracking (SCC) of magnesium alloys
, 2022 S.341-380Stress corrosion cracking (SCC) of Mg alloys is intergranular (IGSCC) or transgranular (TGSCC). A continuous or nearly continuous second phase, typically along grain boundaries, causes IGSCC by micro-galvanic corrosion of the adjacent Mg matrix.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing
