Programme Chronology
1970s: Creep deformati on behavior of material s initiated with
the support of (UNIDO)
creating the single largest creep testing facility in south
Asia
1980s: Fracture characterisation and fracture mechanics of
engineering materials was initiated
early 1990s: Component Integrity Evaluation Program launched
with co-sponsorship from
World Bank and five other premium industrial organizations.
2002: Technology for Engineering Critical Assessme nt program
launched [10th Five year Plan
programme] : established networks with research organizations
and industries
2008: Technology for Assessment and Refurbishment of Engineering
Materials and Components
program initiated [11th five year plan program]: focused on
selected industrial sectors, to solve
critical life assessment and life enhancement issues of
components.
Today: The mechanical behaviour group at NML is one of the best
experimental groups
anywhere with world class infrastructural facilities and
expertise.
Scope:
Industrial research: sponsor specific mandates executed in a
limited time frame in order to
provide a research/industrial solution. A number of industrial
investigations for a variety of
industries have been carried out under this category. Some of
the beneficiaries are thermal and
nuclear power plants, fertilizer and petrochemical industries,
steel industries, railways and
aviation industries.
Basic research: often the off-shoot of the industrial problems
that require to be scientifically
understood.
Knowledge dissemination and mentoring: throughtieups with differ
ent academia students
are inducted for doctoral, post-graduation and graduation work.
To cater to the industrial
sector, the group periodically organizes symposia, workshop and
specialized training programs.
Often the themes of these programs have direct relevance to
industrial applications and aims to
educate the plant engineers to handle the day to day problems
related to behavior of materials.
