 Dr.
Jaske is Senior Project Manager and Manager of Software for
CC Technologies. He is leading work in the areas of mechanical
integrity, fitness-for-service, and remaining-life assessment
of structures and equipment. This work includes projects on
fatigue, corrosion-fatigue, creep, creep-crack growth, high-temperature
properties, in-service aging, and failure analysis of structural
materials. These projects typically incorporate both analytical
assessments and experimental evaluations of failure lives
and material damage. Much of his work has been concerned with
relating the physical metallurgy of carbon steels, low-alloy
steels, stainless steels, and heat-resistant alloys to their
mechanical properties and in-service aging. His research includes
wrought products, castings, and weldments.
Dr. Jaske has evaluated the effects
of elevated temperatures and corrosive environments on mechanical
properties of materials. He has developed and implemented
fracture-mechanics approaches for assessing creep, fatigue,
and stress-corrosion cracking degradation and failure of engineering
components, such as in-service pressure vessels and piping
that are. He has served on industry and government advisory
groups for life extension and remaining life assessment of
key engineering equipment and facilities. Also, he has developed
computer programs for life assessment of welded steam pipes,
reformer furnace tubes, and pressure vessels.
A major portion of Dr. Jaske's work,
since joining CC Technologies in 1990, has addressed the mechanical
integrity of oil and gas pipelines. He developed a model for
predicting the failure and remaining life of pipelines with
local defects, including crack-like flaws, and commercialized
the CorLAS™ computer program to make the model easily
usable by engineers. His work on pipelines includes evaluations
of stress-corrosion cracks, corrosion flaws, weld defects,
dents, gouges, and dents with corrosion. He utilizes inspection
and operational data to predict failures and remaining service
life and advises companies on implementing and maintaining
appropriate integrity programs.

Integrity
of Oil and Gas Pipelines Performed
numerous projects on evaluating the integrity
of oil and gas pipelines, including failure analyses.
The CorLAS™ computer program was developed
to predict the failure of pipelines with local
defects, including crack-like flaws. An independent
evaluation of available models for assessing
SCC flaws showed that CorLAS™
gave the most accurate predictions of fourteen actual
Canadian pipeline failures. Other projects include
evaluation of stresses during hot tapping, assessment
of dents and gouges, and predictions of fatigue failure.
Fatigue Strength Reduction
Factors for Welds Completed an interpretative
review of fatigue strength reduction and stress
concentration factors for welds in pressure vessels
and piping for the Welding Research Council (Bulletin
432, June 1998). Available procedures for evaluating
the fatigue strength of welded structures were
reviewed and evaluated. Guidelines for developing
weld-joint fatigue strength reduction factors were
developed.
Aging of Nuclear Power Plant
Components Participated in the U.S.
Nuclear Regulatory Commission's Nuclear Plant Aging
Research (NPAR) program to help develop methodology
for residual-life assessment of key safety-related
nuclear-plant components, including evaluation
of the thermal embrittlement of cast stainless
steels.
Remaining Life Assessment Conducted
numerous projects to assess the remaining life of operating
equipment in industrial plants. This work included
testing and examination of material samples and analytical
calculations. Examples of equipment that have been
evaluated include steam-turbine rotors, steam pipes,
reformer furnace tubes, headers, superheater and reheater
tubes, and pressure vessels.
Creep-Fatigue Crack Growth Developed
a fracture-mechanics model and life-assessment approach
for creep-fatigue crack growth interaction effects
and performed creep, low-cycle fatigue, and creep-fatigue
crack propagation experiments on Type 316 Stainless
Steel.
Creep Fracture and Creep-Fatigue
Life of Welded Steam Lines Developed
personal computer codes to help assess the remaining
creep and creep-fatigue life and the potential
for unstable fracture of 2-1/4Cr-1Mo and 1-1/4Cr-1/2Mo
welded steam pipes, including seam-welded hot reheat
steam lines.
Failure Analyses Performed
failure analyses of various components used in industrial
equipment, including the failure of a large motor shaft,
the failure of a generator rotor, the failure of a
mold used for casting bronze alloys, steam pipe failures,
and failures of fired furnace tubes.
Long-Life Corrosion Fatigue
Evaluation for the Development of Alloys Used in
Paper-Making Equipment Performed long-life
(107 to 109 cycles to failure)
corrosion-fatigue studies of cast alloys--bronze,
martensitic stainless steel, austenitic stainless
steel, and duplex stainless steel--in white water
(low pH, chloride, sulfate, thiosulfate) environments;
to realistically simulate expected service conditions,
tests have been performed at low stresses for periods
of several months to more than one year. |
