Sample libraries to expedite materials experience for design: A survey of global provision

Material libraries provide designers with a hands-on resource to understand materials and related properties beyond what is possible through datasheets, catalogues and online resources. This paper reports a survey of global material libraries (n= 17) to establish their variety in character and features. Directors, curators, managers and librarians participated in the survey. The principal motivation was to expose the make-up of existing libraries against a series of principal criteria, such that the conception of new material libraries and the development of existing libraries can progress in an informed manner and not as isolated ventures. Material libraries were found to predominantly support Interior Design, Industrial Design and Architecture. A plurality of approaches was uncovered, amongst which no single benchmark could be identified. Thus individual librarians and library project managers are recommended to scrutinize the categorized results (under 'facilities and foundations of libraries'; 'who visits material libraries and why'; 'the content of material library inventory and information supply'; 'presentation systems for displaying and making inventory accessible'; and 'reflections on how material libraries might evolve') to define their own bespoke approach to experiential learning and knowledge exchange through material exposure and evaluation.


Method for Dynamic Material Property Characterization of Soft-Tissue-Mimicking Isotropic Viscoelastic Materials Using Fractional Damping Models
Martin, Bryn A.; Kutluay, Umit; Yazıcıoğlu, Yiğit (ASTM International, 2013-09-01)
Characterization of the mechanical properties of human-tissue-mimicking silicone elastomers is important for producing accurate tissue models for experimentation. However, the viscoelastic and frequency-dependent material properties of elastomers are difficult to quantify. We present a material characterization technique for a silicone elastomer used to mimic human soft tissue based on generalized-Maxwell-type material models with and without fractional dissipating mechanisms. The silicone specimens were pr...
Design of Retaining Walls Using Big Bang-Big Crunch Optimization
Camp, Charles V.; Akin, Alper (American Society of Civil Engineers (ASCE), 2012-03-01)
A procedure is developed for designing low-cost or low-weight cantilever reinforced concrete retaining walls, with base shear keys, using big bang-big crunch (BB-BC) optimization. The objective of the optimization is to minimize the total cost or total weight per unit length of the retaining structure subjected to constraints on the basis of stability, bending moment, and shear force capacities and the requirements of the American Concrete Institute (ACI 318-05). An iterative population-based heuristic sear...
Assessment of improved nonlinear static procedures in FEMA-440
Akkar, Dede Sinan; Metin, Ash (American Society of Civil Engineers (ASCE), 2007-09-01)
Nonlinear static procedures (NSPs) presented in the FEMA-440 document are evaluated for nondegrading three- to nine-story reinforced concrete moment-resisting frame systems. Evaluations are based on peak single-degree-of-freedom displacement, peak roof, and interstory drifts estimations. A total of 78 soil site records and 24 buildings with fundamental periods varying between 0.3 s-1.3 s are used in 2,832 linear and nonlinear response-history analyses to derive the descriptive statistics. The moment magnitu...
ELMEZAINI, N; CITIPITIOGLU, E (American Society of Civil Engineers (ASCE), 1991-10-01)
A practical and powerful technique for the discrete representation of reinforcement in finite element analysis of prestressed and reinforced concrete structures is presented. Isoparametric quadratic and cubic finite elements with movable nodes are developed utilizing a correction technique for mapping distortion. Reinforcing bars and/or prestressing tendons are modeled independently of the concrete mesh. Perfect or no bond as well as any bond-slip model can easily be represented. The procedure is succes...
Plastic deformation induced microstructure evolution through gradient enhanced crystal plasticity based on a non-convex Helmholtz energy
Klusemann, Benjamin; Yalçınkaya, Tuncay (Elsevier BV, 2013-09-01)
A gradient crystal plasticity model in the framework of continuum thermodynamics and rate variational formulation is presented for the description of plastic deformation patterning in a system with non-convex energetic hardening. The paper focuses on the extension of the 1D deformation patterning analysis of Yalcinkaya et al. (2011) to 2D for monotonic loading histories. Solution algorithm is based on the simultaneous solution of displacement and plastic slip fields, which have been considered as primary va...
