Near surface mounted CFRP laminates for shear strengthening of concrete beams [PDF]
Cement and Concrete Composites, 2006 A Near Surface Mounted (NSM) strengthening technique was developed to increase the shear resistance of concrete beams. The NSM technique is based on fixing, by epoxy adhesive, Carbon Fiber Reinforced Polymer (CFRP) laminates into pre-cut slits opened in the concrete cover of lateral surfaces of the beams.

Modeling of bond between near-surface mounted CFRP laminate strips and concrete [PDF]
Computers and Structures, 2004 Near-surface mounted (NSM) laminate strips of carbon fiber reinforced polymer (CFRP) is a promising technique for increasing the flexural and the shear strength of deficient concrete members.

Torsional Strengthening of RC Beams with Continuous Spiral Near-Surface Mounted Steel Wire Rope
International Journal of Concrete Structures and Materials, 2020 The strength of reinforced concrete members can be enhanced using externally bonded reinforcement (EBR) and near surface mounted (NSM) methods. However, small number of studies has adopted the NSM method for torsional strengthening. To date, no study has
