文摘
- •
The challenges of full-scale analysis of realistic FRP strengthened plates are faced.
- •
Geometrically irregular strengthening schemes and delaminated regions are addressed.
- •
A multi-layered, triangular FE incorporating high order kinematics is developed.
- •
The shear/bending mode decomposition is generalized to face the multi-layered FE locking.
- •
Irregularities effect on stress concentrations is quantified on an FRP strengthened wall.
