Material Mechanics Explained Intuitively With Nearly Zero Mathematics Volume 3

This book covers dynamic material mechanics, which focuses on the behavior of materials under time-varying loads, such as impacts, vibrations, and shocks. This is the TOC: Static load VS dynamic load 3 The basics of dynamic load 4 Deterministic and non-deterministic loads 7 Dead loads and live loads 9 Free vibration, eigen-frequency, and forced vibration 11 Free vibration often take place AFTER forced vibration? 13 Eigenvalue 14 Every structure has a natural frequency? 15 Frequency of ground movement and resonance 17 The key is the rhythm... 18 How to evaluate? 20 Rhythmic vibrations 22 Which frequency is "better"? 23 What are examples of high natural frequency structure and material? 26 Different floors have different natural frequencies - WHY? 29 Mode shapes and material 31 What are examples of low natural frequency structure and material? 34 Stiffness... 36 How to measure resonance? 38 Why resist swaying and bending? 39 How does damping offset vibration in buildings? 41 Types of damping devices 44 Wind load VS earthquake load VS flood load 47 A compromise... 51 Modal complexity 53 Other dynamic loads 55 Why high energy often corresponds to low frequency, and vice versa? 58 All about seismic waves 61 The role of Inertia 64 Dynamic VS static degrees of freedom 66 Multiple resonance 68 Formulating the equations... 69 Mass Matrix Construction 71 Matrices in dynamic systems 73 Evaluating dynamic response 76 Modal time-history analysis, direct integration, and response spectrum analysis 78 Harmonic and periodic excitations 80 High strain rate behaviour 83 Dynamic failure 85
