Enhanced concrete crack closure with hybrid shape memory polymer tendons

•Novel hybrid tendons are presented as crack-closure system for concrete.•They consists of a pre-stressed inner core an outer sleeve of Shape memory PET.•During manufacturing the inner core is put into tension and the outer PET in compression.•Once the crack occurs the tendon is activated via heatin...
