Abstract: A criterion for low-cycle fatigue is developed which supposes that the segment of strain hysteresis associated with work-hardening is a measure of damage. On the basis of this “damage” work ...

Abstract: The plastic strain-life relation for several ductile materials is examined in both air and vacuum and interpreted in light of the well-known plastic strain (ΔξP ) life (N) relation, N1/2 ΔξP ...

Abstract: We consider a distributed parameter system of parabolic type and N controllers which can be positioned at p(p > N) different points on the system’s spatial domain. Using relaxed control ...

Abstract: A double underreamed drilled shaft with 5 ft (1.5 m) diameter bells and 2.5 ft (0.8 m) diameter shaft was instrumented and load tested. Results of the load test indicate that the underreams act independently at very small ...

Abstract: The site of the 10‐story parking garage contained soft to medium consistency residual silty clays overlying carbonate rock formations. This rock contains numerous solution cavities and fracture zones with angles of dip ...

Abstract: AbstractNarrow, tropopause-level wind speed maxima known as jet streams or jets are among the most ubiquitous structural characteristics of Earth?s atmosphere. Two species, the polar and subtropical jets, can be observed ...

Abstract: This paper describes the experimental analysis of joints made with threaded steel rods epoxy-glued into high-density hardwood. Seventy specimens of 10 different types were tested until failure with a pull-pull device. The ...

Abstract: Recommendations are presented for determining unit point and shaft resistances for precast prestressed concrete piles embedded in the Yorktown Formation, the bearing stratum for most major structures in tidewater Virginia. ...
