Anisotropic Superelasticity of Textured Ti-Ni Sheet
Thamburaja, P.; Gao, S.; Yi, S.; Anand, Lallit (2002-01)A recently developed crystal-mechanics-based constitutive model for polycrystalline shape-memory alloys (Thamburaja and Anand [1]) is shown to quantitatively predict the in-plane anisotropy of superelastic sheet Ti-Ni to ... -
A Constitutive Model for the Mechanical Behavior of Single Crystal Silicon at Elevated Temperature
Moon, H.-S.; Anand, Lallit; Spearing, S. Mark (2002-01)Silicon in single crystal form has been the material of choice for the first demonstration of the MIT microengine project. However, because it has a relatively low melting temperature, silicon is not an ideal material for ... -
A continuum theory of amorphous solids undergoing large deformations, with application to polymeric glasses
Anand, Lallit (2003-01)This paper summarizes a recently developed continuum theory for the elastic-viscoplastic deformation of amorphous solids such as polymeric and metallic glasses. Introducing an internal-state variable that represents the ... -
A new digital image correlation algorithm for whole-field displacement measurement
Su, C.; Anand, Lallit (2003-01)We have developed a new digital image correlation (DIC) algorithm for non-contact, two-dimensional, whole-field displacement and strain measurement. Relative to existing algorithms, our algorithm substantially reduces the ... -
Non-linear mechanical behavior of polydimethylsiloxane (PDMS): application to the manufacture of microfluidic devices
Huang, Regina; Lele, Suvrat P.; Anand, Lallit (2004-01)Soft-lithography is a low-cost and convenient microfabrication technique that is becoming increasingly popular in the manufacture of microfluidic devices. A typical elastomer used in soft-lithography is polydimethylsiloxane ... -
Non-linear mechanical behavior of the elastomer polydimethylsiloxane (PDMS) used in the manufacture of microfluidic devices
Huang, R. C.; Anand, Lallit (2005-01)Polydimethylsiloxane (PDMS) is the elastomer of choice to create a variety of microfluidic devices by soft lithography techniques (eg., [1], [2], [3], [4]). Accurate and reliable design, manufacture, and operation of ... -
A Novel Testing Apparatus for Tribological Studies at the Small Scale
Gearing, B.P.; Anand, Lallit (2002-01)A novel flexure-based biaxial compression/shear apparatus has been designed, built, and utilized to conduct tribological studies of interfaces relevant to MEMS. Aspects of our new apparatus are detailed and its capabilities ... -
Studies on Nano-Indentation of Polymeric Thin Films Using Finite Element Methods
Shen, Xiaojun; Yi, Sung; Anand, Lallit; Zeng, Kaiyang (2002-01)In this paper, the numerical simulation for nano-indentation is performed to measure time-dependent behavior of polymeric films. The possibility to extract the relaxed shear modulus of the polymer is evaluated using a rigid ... -
A theory of amorphous polymeric solids undergoing large deformations: application to micro-indentation of poly(methyl methacrylate)
Ames, N.M.; Anand, Lallit (2004-01)Although existing continuum models for the elasto-viscoplastic response of amorphous polymeric materials phenomenologically capture the large deformation response of these materials in a reasonably acceptable manner, they ...
