Mircea Raţiu was born October 11, 1923 in city Turda, Romania.
Educated at Polytechnic Institute Timisoara, Romania -IPT- he graduated as Electro-mechanical engineer in 1948, and received the Doctor of Engineering degree in Strength and Testing of Materials in 1967. He lived in city of Timisoara until 1978, when was obliged to leave his native country and he settled with his wife in Oakland, California, USA, as political refugees.
He started his career in 1948 as assistant/associated professor at Strength of Materials chair, IPT ;He was fired for political reason first in 1951 and later in 1956. In 1968-1978 he was assigned as advisor for doctoral studies in Strength and Material Testing. In 1994, the University Polytechnica Timisoara conferred the title of Honorary Professor. He jointed the research programs (1950-1969) of the Material Mechanics Laboratories of Timisoara, Romanian Academy Branch.
His technical activity in Romania started as design engineer for cranes and mechanical testing equipment (1950-1954) at the Machine Design Institute Timisoara. Transferred to the National Institute of Metrology (1954-1969), he established the National Standard Laboratories Force/Hardness Measurements, and Mechanical Testing in Timisoara.
He designed/built the original-patented standard equipment; for his achievements he was honored with the Scientific Merit Order (1966). In 1969 he is assigned as scientific director to organize the Welding and Material Testing Institute ISIM- in Timisoara. He managed the research/ development of welded structures design -fabrication. For his contributions to Danube Bridge Construction ”Giurgeni-Vadul Oii” he is awarded in 1972 with the Work Order. Discharged in 1975,he continued his activity as principal researcher until June 1978.
In the USA his activity was dedicated to technical assistance for the safety qualification of nuclear power plants, in construction and/or operations. As senior engineer at EDS Nuclear, San Francisco (1978-1983), he provided seismic design qualifications for power plant components and implemented the Fracture Mechanics Analysis Programs for protection against brittle failure for pressure vessels and piping during operation cooling accident. He resumed this activity as senior technical specialist at IMPELL Corp., in Walnut Creek and, later, in San Ramon, California-(1983-1993)- developing: Elastic-plastic Stress Analyses for the integrity/operability qualification; Fracture Control Plans for pressure parts, with service induced damages; Plant Life Extension and Failure Analyses. After retirement (1994) as consultant /advisor, in California, at: TRANSNUCLEAR WEST, Fremont DUKE Engineering Services, San Ramon, CALCET California Consulting Engineering/Technology, San Leandro, VECTRA Technologies, San Jose, a.o. provided: fitness for service validations/structural integrity analyses for: power plants, welded structures, and containment system for spent nuclear fuel. His expertise in Stress Analysis, Fracture Mechanics, Mechanical Metallurgy, Welded Structure Design, and Metrology is mentioned in “Who’s Who” Science Europe (1978), Marquis “Who’s Who” Science and Engineering (1993). His priority to Foundation of Sclerometry are revealed in the OIML International Organization Legal Metrology documents.
He published/ presented over 150 papers/transactions in: USA, Germany, France, URSS, Switzerland, Hungary, Romania. He published books in Romania as coauthor: “Force Measurement Technique” (1961;1964); “Testing Analyses Metals” (1966), and author: “Reliability Applications Mechanical Design” (1973), “Sclerometry Elements” (1998), “Strength Reliability Researches” (2003), ”Material Testing Metrology” (2004).
