✦ Synopsis

Abstract

The main aim of the investigations is to compare and evaluate several models of martensitic transformation and transformation‐induced plasticity (TRIP) for the bearing steel 100Cr6, with and without taking stress dependence into account. At first, the investigations are based on measured data of tension‐compression tests with small probes undergoing martensitic transformation at a special testing machine. Secondly, we consider martensitic quenching of thin conical rings. In case of symmetric quenching by gas nozzles, the rings undergo distortion the major part of which can only be explained by TRIP, while the usual plasticity is negligible. The 3D‐simulations will be compared with experimental data.

## Abstract Solvent effects play a crucial role in mediating the interactions between proteins and their ligands. Implicit solvent models offer some advantages for modeling these interactions, but they have not been parameterized on such complex problems, and therefore, it is not clear how reliable

The purpose of this study is to investigate the quantitative relationship between the width of the glass transition, DT g , and glass fragility or activation energy for structural relaxation. The ultimate objective is the estimation of structural relaxation time as a function of temperature from the
