  • The state of deformation, strain, and stress within a body may be determined only when a sufficient set of boundary conditions (displacement and traction) is defined. Sometimes, the complete set of boundary tractions may not be available as in the case of contact regions between two bodies. The solution of the Ill-Posed Problem of Contact Stress Reconstruction (IPP of CSR), despite its numerous physical applications, has received scant attention in the literature so far. Techniques for the solution of such problems, for example, may be employed in characterizing boundary tractions at inaccessible regions of critical components in sensitive mechanical equipmentmore » or to determine tractions in physical truncations needed in partial mesh discretization of a body. The numerical solution of the IPP of CSR simulates the exploitation of a combination of experimental and numerical techniques in a complementary fashion. This paper presents a boundary element formulation with explicit calculation of the sensitivities in an optimization framework for the solution of the IPP of CSR from measurements located at discrete locations of a solid. The magnitude, location, and extent of the contact stresses are defined in terms of load and geometric parameters.« less

  • The author suggests, in colloquial fashion, that the temporal profile of the ion beam might be of interest in the study of heat transport from targets. He cites several personal examples.
  • In August of 1990, the Department of Energy (DOE) awarded the Parsons Corporation a contract to perform architectural/engineering (A/E) remedial design (RD) services for the Fernald Environmental Management Project (FEMP). Complicating the implementation of the first RD contract were other contract firsts, such as (1) working initially under DOE as a prime contractor, then under a management and operations contractor as a subcontractor, and, currently, under an environmental restoration management contractor as a subcontractor; (2) operating under the then new DOE risk-sharing liability and indemnification regulation; and (3) operating under new, legally enforceable DOE nuclear safety regulations. In addition tomore » these contract firsts. Were a number of funding and technical changes resulting from shifting priorities in the environmental program. These changes include (1) a decreased local emphasis on implementing innovative remediation technologies; (2) promoting ways to accomplish remedial activities faster, better, and cheaper without sacrificing safety; (3) a new emphasis on land use planning as a means of formulating cleanup levels; and (4) the increased involvement of the public.« less
