This work aims to model the mechanical processes used by tree branches to control their posture despite their increasing weight loading. The two known options for a branch to maintain its orientation are the asymmetry of maturation stress, including reaction wood formation, and eccentric radial growth. Both options can be observed in nature and influence the stress distribution developed in the branch each year. This so-called "growth stress" reflects the mechanical state of the branch. In this work, a growth stress model was developed at the cross-section level in order to quantify and study the bio-mechanical impact of each process. For illustration, this model was applied to branches of two 50-year-old trees, one softwood \textit{Pinus pinaster} and one hardwood Prunus avium, both simulated with the AMAPSim finite element software. The computed outputs enlightened that, for both Prunus avium and Pinus pinaster, eccentric radial growth is less efficient than the formation of reaction wood to counter increasing gravity stress applied to the branch. For the pine, although eccentric growth does not necessarily act as a relevant lever for postural control, it greatly modifies the profile pattern of mechanical stress and could provide mechanical safety of the branch. This work opens experimental perspectives to understand the biomechanical processes involved in the formation of branches and their mechanical safety.
Here is my obligatory #introduction.
I’ve worked in the fields of #science and #engineering for over two decades. My degrees are in mechanical engineering, but I’ve spent many years both professionally and recreationally crossing over into the computer science realm when it intersects with my interests and projects.
I’ve been a #Linux user since the mid-90s, and I’ve been paid to admin Linux and Unix number-crunching boxes, including Irix, HP-UX, AIX, and other fun OSes that either don’t exist anymore or you probably haven’t heard of.
I enjoy programming, especially #Python, #Golang, and #Julia, although I’ve used another dozen or so languages along the way, everything from FORTRAN to Perl and TCL to Haskell (and lots in between). I’m an electronic hobbyist, and you may find me tinkering with #RaspberryPi and #Arduino boards.
My technical interests also include #woodscience, #mathematics, #numbertheory/#numericalmethods, #statistics, #datascience, #sliderules, and #TeX.
I like making things, so my hobbies include #watercolor, #drawing, #woodworking and #blacksmithing. I also love #books and reading, with a proclivity towards #history, #art, #religion, #BiblicalCriticism, #scifi, #fantasy, and classical #literature.
I like to listen to and play #music. I play #guitar and dabble in lots of other instruments. My favorite styles of music are #folk, #celtic, and #Americana, but I enjoy a diverse mix of genres, so you might catch me listening to Cat Stevens and Tom Lehrer one day and Johnny Cash and Eminem the next.
I love #nature, mountains and oceans, #hiking, and #birding. I like to #travel to new places, see new things, and experience the local food and culture. Speaking of #food, I like to #cook.
I also like gaming, especially on my #Nintendo #Switch and #Steamdeck.
