Crack Growth in Compressive Stress Fields
(Polytechnic University of Puerto Rico, 2013)
To understand how to analyze
Damage Tolerance in an aerospace component
loaded in compression one must first obtain correct
Fatigue Crack Growth curves. Once the fatigue
data curves are correct one could then move
forward ...

Assembly fit-up issue: investigation of a first stage high pressure gas turbine rotor
(Polytechnic University of Puerto Rico, 2018)
A Gas Turbine engine generates
mechanical energy from a combustible fuel. This
mechanical energy could be converted into
electrical power by means of a rotating shaft as
opposed to the pressurized thrust generated on ...
Data Center Design and Airflow Management (Insight into Increasing Performance and Efficiency)
(Polytechnic University of Puerto Rico, 2015)
The formation of hot spots in data
centers is usually caused by the inability to
properly distribute the airflow and not for the lack
of capacity by the cooling system. Airflow
management is essential to reduce the ...
