Effect of Bit Configuration in Impact Penetration Tests with Button Bits
Computer simulation of percussive rock drilling requires appropriate numerical models for the interactions among the drill body, rod, rod joint, bit, and rock.

A method for measuring the contact area in instrumented indentation testing by tip scanning probe microscopy imaging [PDF]
The determination of the contact area is a key step to derive mechanical properties such as hardness or an elastic modulus by instrumented indentation testing. Two families of procedures are dedicated to extracting this area: on the one hand, post mortem

Penetration depth for shallow impact cratering [PDF]
We present data for the penetration of a variety of spheres, dropped from rest, into a level non-cohesive granular medium. We improve upon our earlier work [Uehara {\it et al.} Phys. Rev. Lett. {\bf 90}, 194301 (2003)] in three regards. First, we explore

Material characterization at high strain by adapted tensile tests [PDF]
The strength of materials at high strain levels has\ud been determined using the so-called Continuous-Bendingunder-\ud Tension (CBT) test. This is a modified tensile test\ud where the specimen is subjected to repetitive bending at the\ud same time.

A study on plant root apex morphology as a model for soft robots moving in soil. [PDF]
Plants use many strategies to move efficiently in soil, such as growth from the tip, tropic movements, and morphological changes. In this paper, we propose a method to translate morphological features of Zea mays roots into a new design of soft robots ...

Experimental Study on Gas Flow and Aerosol Deposition Characteristics in Micro-channel
Aerosol retention occurs when it penetrates through micro-leakage paths within the containment after nuclear reactor accidents. Aerosol particles are deposited by mechanisms such as gravity sedimentation, Brownian diffusion, entrance effect, and ...

Analysis of nanoindentation of soft materials with an atomic force microscope [PDF]
Nanoindentation is a popular experimental technique for characterization of the mechanical properties of soft and biological materials. With its force resolution of tens of pico-Newtons, the atomic force microscope (AFM) is well-suited for performing ...
