(Dept. of Theoretical and Applied Mechanics (UIUC), 1998)The thermoelastic properties of several common woven glass/epoxy substrate materials were characterized in both the warp and fill directions. Five common commercially pressed cores (1080, 2116, 2313, 3313, 7628) were ...

(Department of Theoretical and Applied Mechanics (UIUC), 200005)Worthington jets are a familiar sight in light rain upon puddles and ponds. These narrow vertical jets are formed by the radial collapse of the liquid "craters" produced by the impacting rain drops. Such jets can also be ...

(Department of Theoretical and Applied Mechanics (UIUC), 200101)Linear and nonlinear analyses of thermal convection with a variable "buoyancy factor", which is defined as the product of thermal expansion coefficient and gravitational acceleration, are investigated for a fluid layer ...

(Department of Theoretical and Applied Mechanics (UIUC), 200101)In the design of explosive systems the generic problem that one must consider is the propagation of a welldeveloped detonation wave sweeping through an explosive charge with a complex shape. At a given instant of time the ...

(Department of Theoretical and Applied Mechanics (UIUC), 200105)When poured into a container, cohesive granular materials form lowdensity, open granular aggregates. If pressed upon with a ram, these aggregates densify by particle rearrangement. In this paper we introduce experimental ...

(Department of Theoretical and Applied Mechanics (UIUC), 200108)We consider a recent experiment of Kundler and Finkelmann (1995), who subjected an aligned specimen of nematic elastomer to uniaxial extension and observed the formation of striped domains. Working with an energy density ...

(Department of Theoretical and Applied Mechanics (UIUC), 200108)The isochoric extension of a cylindrical, nematicelastomeric specimen is studied. Numerical solutions of the resulting boundaryvalue problem predict that, for sufficiently large extensions, there exists a region surrounding ...

(Department of Theoretical and Applied Mechanics (UIUC)Los Alamos National Laboratory (LANL), Los Alamos, NM, 200109)This paper summarizes recent work at the University of Illinois on the fundamental mechanisms of hydrogen embrittlement. Our approach combines experimental and theoretical methods. We describe the theoretical work on hydride ...
