Mechanical Behavior and Constitutive Model of Basalt-Fiber Textile-Reinforced Engineered Cementitious Composite Under Off-Axis Tension
Highlights Strength higher at 0°/15° than 30°/45°; ultimate strain opposite. 0° lay-up is optimal for strength-critical and viable for energy-critical cases. Crack opening is 30–50 μm for all loading cases, showing excellent crack control. A phenomenological constitutive model well captures off-axis angle behavior. Abs...
