Hi,
I am using the VCCT method to model crack propagation and I am finding the value of G/Gc is too large for any sensible time step (1e-25).
I am attempting to incorporate a time incrementation scheme into my UMAT which monitors EFENRRTR and modifies the time step (or PNEWDT) according to it's value.
河海大学创建于1915年，校本部位于南京市区风景秀丽的清凉山北麓，并在常州市新北区、南京市江宁区设有校区，总占地面积2300余亩。河海大学是以水利为特色，工科为主，多学科协调发展的教育部直属全国重点大学，是国家“211工程”重点建设的高校之一。河海大学的发展得到了党和国家的重视和关怀。1985年，邓小平同志亲笔题写了校名“河海大学”；1995年80周年校庆，江泽民同志为学校题词：“面向未来，开拓进取，进一步发展水利教育事业”；2005年90周年校庆，温家宝总理视察学校并作重要讲话，对学校寄予了殷切期望。继往开来的河海大学正向着高水平特色研究型大学迈着坚实脚步。
河海大学力学与材料学院前身为河海大学工程力学系、材料科学与工程系，创建于1959年，是学校历史最悠久的系科之一。现有工程力学国家重点学科、力学一级江苏省重点学科、国家工科基础课程（力学）教学基地，国家级力学实验教学示范中心、国家力学教学创新团队、国家精品课程、力学一级博士点、力学一级博士后流动站和江苏省材料试验示范中心。为提高本学科的综合学术竞争力，建设好国家重点学科，现面向海内外公开招聘杰出人才，具体招聘事宜如下：
一、招聘专业、方向
Dear Colleagues,
Please consider to attend the symposium entitled "Lithium ion batteries - when chemistry meets mechanics" at the occasion of the Joint Society of Engineering Science (SES) 50th Annual Technical Meeting and ASME-AMD Annual Summer Meeting, July 28-31, 2013, at Brown University.
The description of the symposium is attached below.
Dear Colleagues,
The Thirteenth
Pan-American Congress of Applied Mechanics (PACAM XIII) will be held in
Houston, TX, USA. The conference dates are May 22-24th, 2013.
We cordially invite you to participate in Phononics 2013: The Second International Conference on Phononic Crystals/Metamaterials, Phonon Transport and Optomechanics – to be held in Sharm El-Sheikh, Egypt, from June 2–7, 2013. The conference covers the following themes:
(1) phononic crystals, (2) acoustic metamaterials, (3) wave propagation in periodic structures, (4) nanoscale phonon transport, and (5) optomechanics.

Nonlinear vibration of a nanoplate embedded on a Pasternak-type foundation using nonlocal continuum theory
BY: Payam Soltani, V. Kamali , O. Pashaei Narenjbon, A. Farshidianfar
Abstract:
Nonlocal plate continuum model is utilized to investigate the nonlinear vibration behaviour of a singlelayer
nanoplate. The isotropic nanoplate is assumed to be embedded on a Pasternak-type elastic foundation with the
The paper by Carta G. and Stochino F. presents two alternative approaches for the study of reinforced concrete beams under blast loads. In the first approach, the beam is modeled by means of Euler–Bernoulli’s theory and its elastic–plastic behavior is expressed through a new nonlinear relationship between bending moment and curvature. In the second approach, instead, the beam is idealized as a single degree of freedom system.
Based on several requests, the deadline to submit abstracts for the Pan American Congress of Applied Mechanics XIII has been extended to the 1st of February. This years PACAM will be held in Houston, TX--the first time PACAM is being held in North America! The conference will feature plenary talks by Professors Alan Needleman, K. Ravichandar and Roger Fosdick.

Dear Colleagues,
The new deadline for abstract (plain text, 400 word limit) submission is now January 28, 2013.
The 4th conference "Nonlinear Dynamics -2013" will be held from 19 until 22 June, 2013 in Sevastopol (Ukraine).
