Langhaar’s academic achievements earned him international recognition for numerous areas of solid mechanics and applied mathematics. He authored two widely used graduate textbooks:
227:. At Convair he worked on aircraft design problems involving plates and shells, buckling, diagonal tension beams, plate-stringer combinations, cut-outs in shells, and fuselages.
193:, he met his future wife, Isabelle Babcock, a school teacher, whom he married in 1937. He returned to Lehigh University later that year and in 1940 obtained his Ph.D. in
