Abstract: A relatively simple and general constitutive model of interface behavior in quasi‐brittle materials is presented. It is assumed that both hardening and softening behaviors are governed by the same Mohr‐Coulomb‐type fracture ...

Abstract: A method is developed to estimate the mean texture depth (MTD) value, which to some extent represents pavement quality, using measurements from a microphone mounted underneath a moving vehicle. Such measurements will include ...

Abstract: Failure modes of polycrystalline alumina in compact-tension specimens were studied using the scanning electron microscope. Microcrack propagation was monitored under large magnification. Starting with a preexisting chevron ...

Abstract: Certain materials exhibit a capability to heal with time. Healing implies that microcracks and microvoids reduce in size, with a corresponding increase in stiffness and strength, features that are exactly the opposite of ...
