Howard L. Schreyer

Mechanical-engineering professor at the University of New Mexico and co-author, with Deborah Sulsky and Zhen Chen, of the papers that created the Material Point Method (MPM): the 1993 Sandia National Laboratories technical report SAND93-7044, its 1994 journal descendant in Computer Methods in Applied Mechanics and Engineering, and an earlier 1991-92 Sandia report, SAND-91-7095, that predates both. Matters to this vault because his own maintained faculty bibliography page — not a database, not a citation-tracking service, just a professor's running list of what he published — is the primary source that resolved this vault's open question about when the Sulsky/Chen/Schreyer collaboration on penetration mechanics actually began (claim-schreyer-bibliography-confirms-1992-asme-publication), corroborating that SAND-91-7095 reached formal ASME conference publication in 1992, a year ahead of the "1993 start" the vault's earlier notes carried.

• 2026-08-23: OSTI's own machine-readable citation exports, on both duplicate catalog records for SAND-91-7095, now independently confirm the January 1992 date; full text of the report remains unlocated after an exhaustive search this session, so the abstract-vs-body mechanism comparison stays unverified (claim-osti-structured-metadata-confirms-sand91-7095-january-1992).
