文摘
- •
The dynamic characteristics of polypropylene fiber reinforced mortar (PFRM) are investigated under compressive impact loading.
- •
The effects of water–cement ratios, fiber contents and strain rates, on the blast resistance performance of PFRM are studied.
- •
The dynamic performance of PFRM is significantly affected by strain rates.
- •
A dynamic constitutive law is derived for PFRM considering material damage.
