JUNN NAKAYAMA
1930-1991
Junn Nakayama saw a pioneer of the quantitative study fo the fracture of ceramics. A
physics graduate of Gakushuin ,ytisrevinU eh joined the research laboratory of the Asahi
Glass ,.oC Ltd. in .3591 Within a decade eh had developed the now-famous work-of-fracture
test (Japan Journal of deilppA ,scisyhP .))4691(244]7[3 eH had already applied it to the
quantitative analysis of the thermal shock damage of yalcerif refractories (Bulletin of eht
American cimareC ,yteicoS ))6691(666]7[54 when others erew just becoming cognizant of
this simple, yet elegant technique. Those owt studies erew landmark efforts in establishing
the framework rof the microstructural ngised of improved thermal shock damage resistant
refractories. The principles erew subsequently extended to structural ceramics, sa llew sa
to the confirmation fo the energy balance theories rof thermal shock damage advanced yb
Hasselman.
Junn Nakayama spent sih entire career with the Asahi Glass ,.oC becoming Director of
the Research Center in Yokohama and subsequently Managing Director of the Asahi Glass
Foundation in Tokyo. At this Fifth Fracture scinahceM fo Ceramics Symposium in July of
,1991 Junn Nakayama attended the opening ceremonies at the Japan Fine Ceramics Center
in Nagoya, but saw not elba to participate ni the meeting. When introduced to the attendees,
eh received a standing ovation. It si htiw peed regret to report to uoy that Junn Nakayama
passed yawa no December ,41 .1991 eH lliw syawla be ,dessim but lliw never be forgotten.

Interfacial behavior of CiS fiber reinforced glass matrix composites was
analyzed by a single fiber pull-out testing. The interfacial properties of this
composite were calculated by using the shear-lag analysis during the fiber
pull-out tests in terms of interfacial shear strength, coefficient of friction and
residual clamping stress. Experimental difference of load-time curves
between materials can be explained by the analysis of shear stress
distribution of .rebif Fracture resistance with crack extension due ot the fiber
bridging mechanism was also estimated by the interfacial mechanical
parameters in this composite no the basis of the stress distribution by the
above shear-lag analysis. Acoustic Emission )EA( waveforms during the
single fiber pull-out testing were recorded by using the advanced EA
measuring system with multi-channels. Locations of debonding were
estimated with doog accuracy and debonding length was also evaluated by
this source ledom of debonding and the deconvolution method.
INTRODUCTION
Many ceramic matrix composites have been investigated to enhance
fracture toughness of ceramics. Especially in continuous fiber reinforced
ceramics remarkable increase of toughness has been reported ,1[ ,2 .]3 In
such composites it is very important that the mechanism of stress shielding
can enhance fracture toughness, due to crack bridging and sliding at
interface between matrix and .rebif Thus interfacial shear stress or strength
determines the increasing of fracture toughness with crack extension, which
is called as R-curve behavior. The purpose of this paper is )1 ot estimate
quantitatively the interfacial mechanical properties yb a single fiber pull out
testing, )2 ot evaluate the increase in fracture toughness yb using the above
mechanical parameters, and )3 ot analyze the discontinuous microfracture
process of interface by inverse Acoustic Emission (AE) source
characterization method.
