Title: Dynamic fracture behavior of single and contacting Poly(methyl methacrylate) particles

Abstract

Fracture behaviors of single, two, and multiple contacting spherical Poly (methyl methacrylate) (PMMA) particles were recorded using high speed synchrotron X-ray phase contrast imaging. A miniaturized Kolsky bar setup was used to apply dynamic compressive loading on the PMMA particles. In both single and two particle experiments, cracking initiated near the center of the particles and propagated towards the contacts. The crack bifurcated near the contact points for single particle experiments, thus forming conical fragments. The crack bifurcation and subsequent conical fragment formation was observed only at the particle-particle contact for two particle experiments. The particles were observed to fracture in hemispherical fragments normal to the contact plane in the multiparticle experiments. The observed failure mechanisms strongly suggest that the maximum tensile stress near the center of the particle is the critical parameter governing fracture of the particles. Moreover, the compressive stress under the contact areas led to the bifurcation and subsequent conical fragment formation.

Fracture mechanisms of glass particles under dynamic compression

Journal Article Parab, Niranjan D. ; Guo, Zherui ; Hudspeth, Matthew C. ; ... - International Journal of Impact Engineering

In this study, dynamic fracture mechanisms of single and contacting spherical glass particles were observed using high speed synchrotron X-ray phase contrast imaging. A modified Kolsky bar setup was used to apply controlled dynamic compressive loading on the soda-lime glass particles. Four different configurations of particle arrangements with one, two, three, and five particles were studied. In single particle experiments, cracking initiated near the contact area between the particle and the platen, subsequently fragmenting the particle in many small sub-particles. In multi-particle experiments, a crack was observed to initiate from the point just outside the contact area between two particles.more »« less

Alpha and recoil track detection in poly(methyl methacrylate) (PMMA)—Towards a method for in vitro assessment of radiopharmaceuticals internalized in cancer cells

Journal Article Myhra, S., E-mail: sverre.myhra@materials.ox.ac.uk ; Chakalova, R. ; Falzone, N. - Review of Scientific Instruments

A method for detection and characterization of single MeV α-particle and recoil tracks in PMMA photoresist by atomic force microscopy (AFM) analysis has been demonstrated. The energy deposition along the track is shown to lead to a latent pattern in the resist due to contrast reversal. It has been shown that the pattern, consisting of conical spikes, can be developed by conventional processing as a result of the dissolution rate of poly(methyl methacrylate) (PMMA) being greater than that for the modified material in the cylindrical volume of the track core. The spikes can be imaged and counted by routine AFMmore »« less

Multiple-phase toughening-particle morphology: Effects on the properties of rubber-toughened poly(methyl methacrylate)

Conference Lovell, P A ; McDonald, J ; Saunders, D E.J. ; ...

Rubber-toughened poly(methyl methacrylate) (RTPMMA) materials were prepared by blending PMMA with multiple-phase toughening particles with radially alternating rubbery and glassy layers. The effects of particle morphology and rubbery-phase volume fraction on the tensile and fracture properties were evaluated. The principal mechanism of deformation operating in these materials, shear yielding with debonding and cavitation of the toughening particles, results in crack-tip blunting. The properties of the RTPMMA materials containing two-layer toughening particles are generally inferior to those containing three- or four-layer toughening particles. 21 refs., 9 figs.
Durability of Poly(Methyl Methacrylate) Lenses Used in Concentrating Photovoltaic Modules: Preprint

Conference Miller, D C ; Gedvilas, L M ; To, B ; ...

Concentrating photovoltaic (CPV) technology has recently gained interest based on their expected low levelized cost of electricity, high efficiency, and scalability. Many CPV systems use Fresnel lenses made of poly(methyl methacrylate)(PMMA) to obtain a high optical flux density. The optical and mechanical durability of such components, however, are not well established relative to the desired service life of 30 years. Specific reliability issues may include: reduced optical transmittance, discoloration, hazing, surface erosion, embrittlement, crack growth, physical aging, shape setting (warpage), and soiling. The initial results for contemporary lens- and material-specimens aged cumulatively to 6 months are presented. The study heremore »« less

Poly(methyl methacrylate) as incorporation medium for spent ion-exchange resin. II. Simulated resin

Journal Article Ghattas, N K ; Ikladious, N E ; Eskander, S B - J. Appl. Polym. Sci.; (United States)

The incorporation and final containment of spent ion-exchange resins into poly(methyl methacrylate) (PMMA) was investigated in the present study. Test blocks of PMMA with 50% incorporated inactive resin were subjected to radiation doses of 10/sup 5/-10/sup 7/ rad at a dose rate of 50 rad/s. The high radiation doses impaired the mechanical properties of the final products. Both compressive strength and hardness decreased with increasing the particle size of the ion-exchange resin. DTA diagrams showed the thermal instability of the final solidification product at about 400/sup 0/C.
