Finite element method-enhanced neural network for forward and inverse problems
Advanced Modeling and Simulation in Engineering Sciences, 2023 We introduce a novel hybrid methodology that combines classical finite element methods (FEM) with neural networks to create a well-performing and generalizable surrogate model for forward and inverse problems. The residual from finite element methods and

Fatigue Strength of AH36 Thermal Cut Steel Edges at Sub-Zero Temperatures
Journal of Marine Science and Engineering, 2023 Cruise ships or yachts that operate in areas with seasonal freezing temperatures have large openings in the outer shell. Those are thermal cut edges, and they are exposed to very low temperatures.

On the study of the dynamic response in 3D additively manufactured auxetic structures [PDF]
EPJ Web of Conferences, 2021 The main aim of this work is to analyse the quasi-static and the dynamic response and deformation behaviour of polymeric auxetic structures manufactured with an SLA (stereolitography) additive manufacturing technique.

Development of a comprehensive database of scattering environmental conditions and simulation constraints for offshore wind turbines [PDF]
Wind Energy Science, 2017 For the design and optimisation of offshore wind turbines, the knowledge of realistic environmental conditions and utilisation of well-founded simulation constraints is very important, as both influence the structural behaviour and power output in ...

Analysis of structured programs
Journal of Computer and System Sciences, 1973 We compare the structural complexity of various classes of structured programs. To achieve this we concentrate on a notion called “reducibility”. Loosely speaking, given two classes of programs C1 and C2, we say that C1 is reducible to C2 (C1≤wC2) if and only if for every program P in C1, there is a program in C2 that computes the same function as P ...
