Effect of waste glass powder, microsilica and polypropylene fibers on ductility, flexural and impact strengths of lightweight concrete

Erfan Najaf, Hassan Abbasi, Seyed Mehdi Zahrai

Today, using lightweight structural concrete plays a major role in reducing the damage to concrete structures. On the other hand, lightweight concretes have lower compressive and…

Multiaxial fatigue life prediction for metallic materials considering loading path and additional hardening effect

Muzhou Ma, Xintian Liu

A large number of data have proved that under the same von Mises equivalent strain condition, the fatigue life under multiaxial non-proportional loading is often much lower than…
