- The Material Point Method (MPM) is quickly becoming THE engineering tool for large deformation problems – a key area where finite element methods struggle. This paper highlighted for the first time the severe stress oscillations (previously put down as cell-crossing instabilities) associated with locking issues in the MPM. Mitigating these issues are essential for meaningful stress/strain analysis. Led to Augarde being invited to give a keynote at MPM 2019 (mpm2019.eu) and an open-source MPM code (wmcoombs.github.io/). Presented at international conferences, including: NUMGE2018 (Porto, numge2018.pt), ECCOMAS2018 (Glasgow, eccm-ecfd2018.org) and WCCM2018 (New York, wccm2018.org).
