Fatigue strength analysis of bimetallic sleeve roll by
Figure 1 illustrates a sleeve roll considered for the fatigue risk evaluation when it is used in the 4-stage rolling mill. In the sleeve roll shown in Fig. 1A, a steel shaft is shrink-fitted to a steel sleeve. Since the sleeve is required to have different properties, the bimetallic sleeve is used as the outer and inner layers.

Tensile behavior of half grouted sleeve connections
An ultra-high-performance concrete (UHPC)-grouted sleeve with a large-diameter seamless steel pipe with threads and bolts was designed. To study the mechanical properties of this grouted sleeve, various factors, such as the grouts type, rebar, thread, and bolts, were considered to conduct a uniaxial tensile test on the grouted sleeve …
