Critical State Soil Mechanics
Critical state soil mechanics is the area of soil mechanics that encompasses the conceptual models that represent the mechanical behavior of saturated remolded soils based on the ''Critical State'' concept. Formulation The Critical State concept is an idealization of the observed behavior of saturated remoulded clays in triaxial compression tests, and it is assumed to apply to undisturbed soils. It states that soils and other granular materials, if continuously distorted (sheared) until they flow as a frictional fluid, will come into a well-defined critical state. At the onset of the critical state, shear distortions \ \varepsilon_s occur without any further changes in mean effective stress \ p', deviatoric stress \ q (or yield stress, \ \sigma_y, in uniaxial tension according to the von Mises yielding criterion), or specific volume \ \nu: :\ \frac=\frac=\frac=0 where, :\ \nu=1+e :\ p'=\frac(\sigma_1'+\sigma_2'+\sigma_3') :\ q= \sqrt However, for triaxial conditions \ \sigma_2'= ...

Imre Lakatos
Imre Lakatos (, ; hu, Lakatos Imre ; 9 November 1922 – 2 February 1974) was a Hungarian philosopher of mathematics and science, known for his thesis of the fallibility of mathematics and its "methodology of proofs and refutations" in its pre-axiomatic stages of development, and also for introducing the concept of the " research programme" in his methodology of scientific research programmes. Life Lakatos was born Imre (Avrum) Lipsitz to a Jewish family in Debrecen, Hungary, in 1922. He received a degree in mathematics, physics, and philosophy from the University of Debrecen in 1944. In March 1944 the Germans invaded Hungary, and Lakatos along with Éva Révész, his then-girlfriend and subsequent wife, formed soon after that event a Marxist resistance group. In May of that year, the group was joined by Éva Izsák, a 19-year-old Jewish antifascist activist. Lakatos, considering that there was a risk that she would be captured and forced to betray them, decided that her dut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Prager
William Prager, (before 1940) Willy Prager, (May 23, 1903 in Karlsruhe – March 17, 1980 in Zurich) was a German-born US applied mathematician. In the field of mechanics he is well known for the Drucker–Prager yield criterion. Willy Prager studied civil engineering at the Technische Universität Darmstadt and received his diploma in 1925. He received his doctorate in 1926 and worked as a research assistant in the field of mechanics from 1925 to 1929. From 1927 to 1929 he habilitated. He was a deputy director at University of Göttingen, professor at Karlsruhe, University of Istanbul, the University of California, San Diego and Brown University, where he advised Bernard Budiansky. Prager was also on a sabbatical at IBM's research lab in Zurich. The Society of Engineering Science has awarded the William Prager Medal in Solid Mechanics since 1983 in his honor. In 1957, he received a Guggenheim Fellowship Guggenheim Fellowships are grants that have been awarded annually s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daniel C
The Wake are a British post-punk, synth-pop and later indie pop band, formed in Glasgow in 1981 by Gerard "Caesar" McInulty (formerly of Altered Images), Steven Allen (drums) and Joe Donnelly (bass), the latter replaced by Bobby Gillespie. Steven's sister Carolyn Allen also joined on keyboards, and remained in the band thereafter. Gillespie left the band in 1983, replaced by Martin Cunning and then by Alexander 'Mac' Macpherson. History The Wake released their first single on their own Scan 45 label, coupling together "On Our Honeymoon" and "Give Up". This single eventually caught the attention of New Order manager Rob Gretton, who helped the band sign to Factory Records in 1982 and record an LP (''Harmony'') at Strawberry Studios in Stockport. This was followed by a number of singles on Factory and its Belgian sister label Factory Benelux. In 1983, The Wake toured with New Order, and thus received critical attention but were often unfavourably compared to their more celebrat ...

Finite Element Analysis
The finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical modeling. Typical problem areas of interest include the traditional fields of structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential. The FEM is a general numerical method for solving partial differential equations in two or three space variables (i.e., some boundary value problems). To solve a problem, the FEM subdivides a large system into smaller, simpler parts that are called finite elements. This is achieved by a particular space discretization in the space dimensions, which is implemented by the construction of a mesh of the object: the numerical domain for the solution, which has a finite number of points. The finite element method formulation of a boundary value problem finally results in a system of algebraic equations. The method approximates the unknown function over the domain. The s ...

John Burland
John Boscawen Burland (born 4 March 1936) is an Emeritus Professor and Senior Research Investigator at the Department of Civil and Environmental Engineering of Imperial College London. In 2016, Burland was elected as a member into the National Academy of Engineering for contributions to geotechnical engineering and the design, construction, and preservation of civil infrastructure and heritage buildings.
